The first example of 3D heterometallic 4d–4f 2,7-naphthanlenedisulfonate compounds [LnAg2(2,7-NDS)(IN)3] (Ln = Sm (1), Eu (2), Gd (3), Tb (4), Dy(5); 2,7-NDS = 2,7-naphthanlenedisulfonate; IN = isonicotinic acid) has been synthesized via hydrothermal reaction and characterized by single crystal X-ray diffraction, elemental analyses, FT-IR spectroscopy, powder X-ray diffraction(PXRD) and thermogravimetric analyses (TGA). X-Ray structural analysis reveals that compounds 1–5 exhibit same well-organized 3D coordination frameworks that are built up by 2D elliptical cylinder shaped [LnAg2(2,7-NDS)(IN)3] layers which are constructed by 1D anionic chains [Ln(2,7-NDS)(IN)3]2 − linking the adjacent Ag(I) ions, and [LnAg(μ2-O)2] units, possessing a 7-connected topology with the Schlafli symbol of {33;411;56;6}.

In this work, we obtained a highly rare three-dimensional Zn(II) MOF, namely [Zn2(BTC)2(L)][(Me2NH2)2]·DMF (BTC3 − = 1,3,5-benzenetricarboxylate, L = N1,N4-bis(pyridin-3-ylmethyl)cyclohexane-1,4-dicarboxamide), and Me2NH2 = dimethylamine cation) by solvo(hydro)thermal method. This polymer was characterized by single-crystal X-ray diffraction, thermogravimetry and solid-state luminescence analysis. The outstanding structural feature of it is (3, 4)-connected net with unprecedented (6 · 82)(6 · 85)(62 · 10)(62 · 83 · 10) topology and self-penetrating motif.

The hydrothermal reaction of rare earth nitrates, CuCN, 2,7-naphthalenedisulfonate (2,7-nds), and isonicotinic acid (Hina) affords a new family of 3D heterometallic 3d-4f coordination polymers, [Ln2Cu(2,7-nds)2(ina)4(H2O)4]·4H2O (Ln = Nd (1), Sm (2), Eu (3), Gd (4); 2,7-nds = 2,7-naphthalenedisulfonate, Hina = isonicotinic acid). Complexes 1-4 are structurally characterized by single crystal X-ray diffraction, elemental analysis (EA), FT-IR spectroscopy (IR), powder X-ray diffraction (PXRD) and thermogravimetric analyses (TGA). X-Ray crystal structure analyses reveal that 1-4 are isomorphous with dinuclear subunit [Sm2(ina)4] binding Cu ions to generate 2D networks. Such 2D networks are pillared by linking 2,7-nds ligands to result in the 3D layer-pillared Ln(III)-Cu(II) coordination architectures. The valence of Cu salts changed in the reaction. In addition, the luminescence properties of 1-3 and the magnetic properties of 3 and 4 have also been investigated.

Two kinds of three-dimensional (3D) coordination frameworks from monometallic to heterometallic, including a charming 3D monometallic complex, namely, [Eu2(mpda)3(H2O)4]n (1) and the first series of novel 3D heterometallic 4d–4f coordination frameworks based on 2,6-dimethylpyridine-3,5-dicarboxylic acid, namely, [Ln2Cd2(mpda)2(bdc)2(SO4)2(H2O)6]n [Ln = Sm(2), Eu(3), Gd(4), Tb(5), Dy(6); mpda = 2,6-dimethylpyridine-3,5-dicarboxylic acid; bdc = 1,4-benzenedicarboxylic acid] have been successfully synthesized under hydrothermal conditions and structurally characterized. Crystal 1 is featured by its interesting 3D chain-layer construction which is formed by the alternative arrangement of chains and layers and exhibits 2-nodal 5, 6-connected 3D network with the Schlafli symbol of {33.43.55.64}{36.46.53}. Complexes 2–6 are isostructural and it reveals that these 3D heterometallic compounds are firstly built by H2mpda ligand. What is worth mentioning is that anionic ligand SO42 − plays a crucial function in the construction building. The two-dimensional (2D) lanthanide-transition heterometallic bilayers [Ln2Cd2(mpda)2(bdc)2]n are pillared by SO42 − subunits forming mixed-ligand complexes with a pillared-layer 3D structure. Complexes 2–6 feature 4-nodal 3, 4, 5, 6-connected 3D frameworks with {4.82}{4.84.10}{42.810.102.12}{42.88} topology. All the complexes are characterized by elemental analyses, FT-IR spectroscopy, Powder X-ray diffraction (PXRD) and thermogravimetric analyses (TGA). Furthermore, the luminescence properties of compounds 1, 3, and 5 and the magnetic properties of complexes 4 and 6 were also investigated in detail.

Reactions of H3tda (H3tda = 1H-1, 2, 3-triazole-4, 5-dicarboxylic acid) with Sm(NO3)3·6H2O, Eu(NO3)3·6H2O, and Tb(NO3)3·6H2O, in the presence of NaOH under hydrothermal conditions, produced three new coordination polymers, [Ln2(tda)2(H2O)3]·5H2O [Ln = Sm (1), Eu (2), Tb (3)]. These compounds were structurally characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TGA), PXRD and single-crystal X-ray diffraction. The single-crystal X-ray diffraction studies of compounds 1–3 reveal that all compounds are three-dimensional porous structures with chiral frameworks. Furthermore, the luminescence studies of compound 2 and 3 in the solid state reveal that they are potential luminescent materials at room temperature.

Through adjustment of the pH value of the reaction system, two series of 3 D lanthanide(III)-copper(I) coordination polymers, namely [Ln2(na)7Cu6Br5(H2O)2] [Ln=La ( 1), Ce ( 2), Pr ( 3), Nd ( 4), Sm ( 5), Eu ( 6), Gd ( 7), Tb ( 8)] and [La2(na)7Cu3Br2(H2O)2]⋅H2O ( 9) (na−=nicotinate), are synthesized hydrothermally and characterized fully. It is worth nothing that these two series of heterometallic compounds are constructed from similar ladder-like Ln-organic chains, but different copper(I) halide clusters. The luminescence properties of the compounds with Nd ( 4), Eu ( 6), and Tb ( 8) are also investigated. [ABSTRACT FROM AUTHOR]

To explore the influence of different carboxylate ligands on the structures of metal–organic frameworks (MOFs), five novel Zn(II) coordination polymer compounds, namely, {[Zn(atz)(bia)]}n (1), {[Zn3(atz)3(tpa)3/2]}n (2), {[Zn2(atz)2(pda)]}n (3), {[Zn4(atz)2(btc)]·4H2O}n (4) and {[Zn2(atz)2(btec)]·H2O}n (5) have been successfully obtained by introducing various secondary auxiliary ligands in Zn(II)–L systems, characterized by elemental analysis, FT-IR, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction (Hatz = 3-amino-1,2,4-triazolate, Hbia = benzoic acid, H2tpa = 1,4-terephthalic acid, H2pda = 1,4-benzenediacetic acid, H3btc = 1,3,5-benzenetricarboxylate, H4btec = 1,2,4,5-benzenetetracarboxylic). Compound 1 features a 2D layer with (4.82) topology, which is further stabilized by hydrogen bonds between the uncoordinated amino groups and uncoordinated oxygen atoms from bia ligands. Compound 2 exhibits a 3D 3,4-connected framework with {4.82.103}{4.82} topology, constructed from Zn(II) ions and μ3-atz ligand. Compound 3 displays a 3D 3,4-connected network with {4.6.8}{4.62.83} topology. Compound 4 possesses a 3D 9-nodal network with a point symbol of {4.8.9}2{4.82}{4.83.9.10}{5.8.9}4{5.82}. Compound 5 shows a 3D 3,4,4-connected framework with {4.82}4{42.83.10}2{84.102} topology. The diverse structures of these five complexes demonstrate that the skeleton of carboxylate ligands have a significant impact on the construction of MOFs. Moreover, the luminescence properties of complexes 1–5 were investigated in the solid state.

The Si+ self-ion-implanted and annealing experiments are conducted on the Si film based on the silicon-on-insulator wafers. The photoluminescence (PL) spectroscopy is used to investigate the luminescence properties of these Si film samples. Plentiful optical structures are observed in the PL spectra, including the D1, D2, D3, X, and the sharp W lines. By comparing the normalized PL intensities recorded by the same spectral experiments, we obtain the optimum self-ion-implanted and thermal annealing parameters. In addition, the defect origins and optical properties of the series of the D peaks and W line are well discussed.

A solid state cathodoluminescence (SSCL) device in which Si3N4 acts as the electronic accelerating layer and poly (2-methoxy-5-(2-ethyl-hexyloxy)-1, 4-phenylene vinylene (MEH-PPV) as the luminescent layer is first designed. Under alternating current bias, SSCL of MEH-PPV is realized. The luminescence peak is located at 600 and 417nm, respectively, corresponding to the exciton emission and the recombination luminescence of lowest unoccupied molecular orbital (LUMO) to highest occupied molecular orbital (HOMO). The intensity of the twopeaks changes with the increasing of the driving voltage nonlinearly. Compared with the device with SiO2 as the accelerating layer, the short wavelength emissions are found to be the same and located at 417nm for both devices, although their accelerating layers are different. It confirms the SSCL theory and the short wavelength is caused by the direct recombination of electrons in LUMO and holes in HOMO. Finally, the accelerating abilities of Si3N4 and SiO2 are compared at high driving voltage, which showed that the accelerating ability of SiO2 is superior to that of Si3N4 at the driving voltage involved.

A luminescence quenching enhanced infrared (IR) detector has been developed to achieve highly sensitive recognition of human body by adding metallic luminescence quenchers. Spherical Ag NPs were mixed with Ru(phen) 3 2+ complex to obtain temperature-sensitive Ag/Ruphen/PVDF films. The relationships among luminescence output, temperature rise and silver addition were investigated and a satisfactory combination of enhanced luminescence factor and temperature change was found with an addition of 5 mol% of 71 nm Ag NPs. It is found that the metal-enhanced luminescence output is insignificant compared to its thermal ingredient since silver provides additional possible electron transfer channels, promoting non-radiative transitions and weakening luminescence. Besides, the Ag NPs induced additional temperature rise bringing further reduction of luminescence. The photothermal effect of Ag NPs can attain a higher temperature change under a certain IR radiation without an observed degradation of luminescence output. A coupled optical-thermal model was established to explain the schematic of the constructed infrared thermal detector. The non-invasive detections of moving and stationary human by the detector were successfully demonstrated. The work tends to provide an engineered optical-thermal model in luminophores and construct highly sensitive luminescence-based infrared thermal detectors.

Abstract: Four novel functional supramolecular metal–organic coordination polymers, [Cd2Cl3(IP)2(NIPH)2](1), [Zn2(IP)2(μ2-SO4)2(NIPH)2]·2H2O(2), [Cd(IP)2(BPDC)](3), [Zn2(IP)2(NDC)2](4) (IP=1-H-imidazo[4,5-f][1,10]-phenanthroline, H2NIPH=5-nitro-isophthalic acid, H2BPDC=4,4′-biphenyldicarboxylic acid, H2NDC=2,6-naphthalenedicarboxylic acid), have been obtained through three types of dicarboxylate linkers. All the four compounds are extended into a 3-D supramolecular framework by hydrogen bonds or weak aromatic interactions. The different structures demonstrate the effect of the dicarboxylate ligands on the formation of such coordination architectures. Compound 1 is a 1-D double-stranded loop-like chain with repeated [Cd4(Cl)4]4+ units connected by H2NIPH ligands. In compound 2, there are two indie 1D zigzag chains jointed by sulfate anions with μ2-bridging mode. With different metal centers, compounds 1 and 2 hold different crystal structures. With different auxiliary dicarboxylate ligands, compounds 3 and 4 exhibit disparate 1D chains. The fluorescence property and thermal stability of all complexes are also investigated.

• The Ruphen/PVDF films shows high temperature-sensitivity (−4.3 %K−1) at room temperature. • We fabricated a thermal imaging device using Ruphen/PVDF films with IR absorber layer. • The low detecting threshold is found as 313 K for the device, and the response time of 1.17 s and NETD of 1.68 K were observed. The accurate temperature measurement with micrometric spatial resolution is difficult to acquire by using conventional contact thermal probes. Noncontact thermal probes possess great potential for future high resolution accurate temperature measurements. Herein, we report a thermometer based on Ruphen-based temperature sensitive paint (TSP) for high-sensitive remote temperature measurement. TSP consisting of Ruphen and PVDF with sharp emission band and high internal quantum efficiency was designed and employed to fabricate a luminescence thermometer prototype for infrared-to-visible converter in this study. The temperature dependent photoluminescence properties of the different Ruphen/PVDF films were analyzed in the range of 283 K to 363 K, and a relatively high thermal sensitivity (−4.3 %K−1 @ RT) was obtained for low Ruphen concentration sample. The as-fabricated temperature sensor prototype can detect a 623 K thermal object with a response time of 1.52 s and a noise equivalent temperature difference (NETD) of 2.40 K. Furthermore, the effect of IR absorber on the imaging performance was also investigated, and an optimized response time of 1.17 s and NETD of 1.68 K were observed. The results indicate that Ruphen/PVDF film is promising for a luminescence thermometer for room temperature mapping. [ABSTRACT FROM AUTHOR]

Two kinds of three-dimensional (3D) coordination frameworks from monometallic to heterometallic, including a charming 3D monometallic complex, namely, [Eu2(mpda)3(H2O)4]n (1) and the first series of novel 3D heterometallic 4d-4f coordination frameworks based on 2,6-dimethylpyridine-3,5-dicarboxylic acid, namely, [Ln2Cd2(mpda)2(bdc)2(SO4)2(H2O)6]n [Ln=Sm(2), Eu(3), Gd(4), Tb(5), Dy(6); mpda=2,6-dimethylpyridine-3,5-dicarboxylic acid; bdc=1,4-benzenedicarboxylic acid] have been successfully synthesized under hydrothermal conditions and structurally characterized. Crystal 1 is featured by its interesting 3D chain-layer construction which is formed by the alternative arrangement of chains and layers and exhibits 2-nodal 5, 6-connected 3D network with the Schlafli symbol of {33.43.55.64}{36.46.53}. Complexes 2-6 are isostructural and it reveals that these 3D heterometallic compounds are firstly built by H2mpda ligand. What is worth mentioning is that anionic ligand SO42− plays a crucial function in the construction building. The two-dimensional (2D) lanthanide-transition heterometallic bilayers [Ln2Cd2(mpda)2(bdc)2]n are pillared by SO42− subunits forming mixed-ligand complexes with a pillared-layer 3D structure. Complexes 2-6 feature 4-nodal 3, 4, 5, 6-connected 3D frameworks with {4.82}{4.84.10}{42.810.102.12}{42.88} topology. All the complexes are characterized by elemental analyses, FT-IR spectroscopy, Powder X-ray diffraction (PXRD) and thermogravimetric analyses (TGA). Furthermore, the luminescence properties of compounds 1, 3, and 5 and the magnetic properties of complexes 4 and 6 were also investigated in detail. [ABSTRACT FROM AUTHOR]

Abstract: The first example of 3D heterometallic 4d–4f 2,7-naphthanlenedisulfonate compounds [LnAg2(2,7-NDS)(IN)3] (Ln=Sm (1), Eu (2), Gd (3), Tb (4), Dy(5); 2,7-NDS=2,7-naphthanlenedisulfonate; IN=isonicotinic acid) has been synthesized via hydrothermal reaction and characterized by single crystal X-ray diffraction, elemental analyses, FT-IR spectroscopy, powder X-ray diffraction(PXRD) and thermogravimetric analyses (TGA). X-Ray structural analysis reveals that compounds 1–5 exhibit same well-organized 3D coordination frameworks that are built up by 2D elliptical cylinder shaped [LnAg2(2,7-NDS)(IN)3] layers which are constructed by 1D anionic chains [Ln(2,7-NDS)(IN)3]2− linking the adjacent Ag(I) ions, and [LnAg(μ2-O)2] units, possessing a 7-connected topology with the Schläfli symbol of {33;411;56;6}. Furthermore, the luminescence properties of compounds 2 and 4 and the magnetic properties of compounds 3 and 5 were investigated. [Copyright &y& Elsevier]

Abstract: Six novel functional metal–organic frameworks, namely, [CdCl(IP)(Hpydc)(H2O)]·2H2O (1), [Cd(IP)(H2imdc)]Cl (2), [Cd(IP)2(H2O)2](1,5-nds)·2H2O (3), [Co(IP)(H2O)4](1,5-nds)·H2O (4), [Zn(IP)(μ2-SO4)(H2O)]·H2O (5), [Zn(IP)(SO4)(H2O)3] (6) (IP = 1-H-imidazo[4,5-f][1,10]-phenanthroline, H2pydc = pyridine-2,6-dicarboxylic acid, H3imdc = imidazole-4,5-dicarboxylic acid, 1,5-nds = 1,5-naphthanlenedisulfonate), were synthesized by controlling auxiliary ligands, metal centers and solvents. In compound 1, Cd(II) is chelated by IP and Hpydc ligands, forming 0D→3D supramolecular structure. Compound 2 is a 1D chain with repeated [Cd(IP)]2+ units connected by H2imdc ligands. With different metal centers, compounds 3 and 4 possess different crystal structures. With solvents regulated, compounds 5 and 6 exhibit distinct structures. In compound 5, sulfate anions show μ2-bridging mode, which results in the formation of 1D chain. In compound 6, only one oxygen atom from sulfate anion coordinates to the metal center, resulting in discrete repeated units. The luminescent properties of 1, 2, 3, 5, 6 and thermal stabilities of all compounds were measured. [Copyright &y& Elsevier]
