The tea tussock moth is a pest that damages tea leaves, affecting the quality and yield of tea and causing huge economic losses. The efficient asymmetric total synthesis of the sex pheromone of the tea tussock moth was achieved using commercially available starting materials with a 25% overall yield in 11 steps. Moreover, the chiral moiety was introduced by Evans' template and the key C-C bond construction was accomplished through Julia–Kocienski olefination coupling. The synthetic sex pheromone of the tea tussock moth will facilitate the subsequent assessment and implementation of pheromones as environmentally friendly tools for pest management.

We have demonstrated a single‐crystal‐to‐single‐crystal (SCSC) transformation from a two‐dimensional noninterpenetrated layer to a microporous three‐dimensional fourfold interpenetrated MOF. The centrosymmetric [Co2(μ2‐OH)(EIBA)3]n (SNUT‐25) transforms into a microporous [Co(EIBA)2]n (SNUT‐26), which is triggered by the reaction time with DMF that acts as a structure‐directing agent (HEIBA = 4‐(2‐ethyl‐1H‐imidazol‐1‐yl)benzoic acid; DMF = N,N′‐dimethylformamide). Despite the distinct structure and coordination arrangements of SNUT‐25 in contrast to SNUT‐26, both Co‐MOFs were synthesized using the same ligand. Fascinatingly, upon introducing a specific quantity of DMF combined with a negligible proportion of nitric acid, SNUT‐25 will progressively and completely transform into SNUT‐26. Under the synergistic induction of solvent molecules and temperature, SNUT‐25 changed from the original two‐dimensional layered structure to the three‐dimensional pore structure of SNUT‐26. In addition, SNUT‐25 and SNUT‐26 are efficient photocatalysts for the degradation of organic dye methyl blue (MB) under visible light irradiation. Surprisingly, the degradation rates of both SNUT‐25 and SNUT‐26 can reach over 96%. In addition, SNUT‐25 and SNUT‐26 also exhibited high electrocatalytic oxygen evolution reaction.

Seven new lanthanide coordination polymers, namely [Ln(cpt)3H2O)]n(Ln = La (1), Pr (2), Sm (3), Eu (4), Gd (5), Dy (6), and Er (7)), which were synthesized under hydrothermal conditions using 4′-(4-(4-carboxyphenyloxy)phenyl)-4,2′:6′,4′-tripyridine (Hcpt) as the ligand. The crystal structures of these seven complexes were determined using single-crystal X-ray diffraction, and they were found to be isostructural, crystallizing in the triclinic P 1 - space group. The Ln(III) ions were nine-coordinated with tricapped trigonal prism coordination geometry. The Ln(III) cations were coordinated by carboxylic and pyridine groups from (cpt)− ligands, forming one-dimensional ring-chain structures. Furthermore, the luminescent properties of complexes 1–7 were investigated using fluorescent spectra in the solid state. The fluorescence sensing experiments demonstrated that complex 4 exhibits high selectivity and sensitivity for detecting Co2+, Cu2+ ions, and nitrobenzene. Moreover, complex 3 shows good capability for detecting Cu2+ ions and nitrobenzene. Additionally, the sensing mechanism was also thoroughly examined through theoretical calculations.

A new zinc(II) metal organic framework has been obtained from the solvothermal assembly of 1,3,5-benzene tricarboxylate and 1,3-bis(imidazole)propane with zinc nitrate in DMAc–H2O (DMAc is N,N -dimethylacetamide), namely {[Zn2 (μ2-OH)(1,3-BIP)(BTC)]·DMAc·2H2O}n (SNUT-6). The product is characterized by single-crystal and powder X-ray diffraction, infrared spectroscopy, thermogravimetric analysis, and elemental analysis. The single-crystal X-ray diffraction reveals that SNUT-6 exhibits a 3D→3D two-fold interpenetrating framework. Furthermore, SNUT-6 demonstrates a highly efficient turn-off fluorescent detection ability for aniline in methanol and shows high sensitivity with a K sv value of 4.771 × 104 M−1. It also shows excellent photocatalytic degradation performance for a three-dye molecular model: rhodamine b, methyl orange, and methyl blue. [ABSTRACT FROM AUTHOR]

Two new Cu(II) complexes namely, Cu(PDC)2.H2O (1) and {[Cu(1,3-BIP)(PDC)(NO3)]·2H2O}n (2) (1,3-BIP = 1,3-di(1H-imidazol-1-yl)propane; HPDC = 5-methyl-4-oxo-1-phenyl-1,4-dihydropyridazine-3-carboxylic acid) have been sythesized and characterized by single crystal x-ray ananlyses, thermogravietr -ic techniques. The single-crystal x-ray diffraction reveals that complex 1 shows a zero-dimensional structure, which is further reinforced through strong intermolecular hydrogen bonding to form a 3D suparmolecular framework. Complex 2 exhibits a one-dimensional ring structure, which are further linked by intermolecular hydrogen bonding to form a 3D supermolecular architecture. The optimized geometric bond lengths and bond angles of complex 1 obtained by using density functional theory (DFT) have been compared with X-ray diffraction values. In addition, the antimicrobial activity of the complex 1 and the photocatalytic activity of the complex 2 were also investigated. [ABSTRACT FROM AUTHOR]

A nitro substituted azo-chalcone derivative 3-(4-(dimethylamino) phenyl) diazenyl)phenyl)-1-(4-nitrophenyl) prop-2-en-1-one (AZOC-4N) and a reference compound 3-(4-(dimethylamino) phenyl) diazenyl) phenyl)-1-phenylprop-2-en-1-one (AZOC-H) were synthesized by Claisen Schmidt reaction. Thermogravimetry, UV-vis and cyclic voltammetry were used to study the influence of the introduction of nitro in the conjugated molecule AZOC-4N on the photoelectric properties. The active layer was further prepared by solution spin coating, and the morphology of the film was characterized by AFM. The electrical memory performance of the device is studied. It is found that the device has the nonvolatile binary write once read many (WORM) memory performances, and the threshold voltage of the device prepared by introducing nitro group into the molecule is lower—1.4 V. Finally, the electrical memory performance of the device is analyzed by theoretical calculation. [ABSTRACT FROM AUTHOR]

Two metal coordination polymers, namely {[Co(MIBA)2]·2H2O}n (SNUT-3) and {[Cu(MIBA)2]·2H2O}n (SNUT-4), where HMIBA = 4-(1H-2-methylimidazol-1-yl)benzoic acid, were prepared by hydrothermal methods. Single-crystal X-ray analysis revealed that the structure of SNUT-3 exhibits a 3D→3D fourfold interpenetrating structure with diamondoid frameworks, while SNUT-4 shows a 2D + 2D → 3D inclined polycatenation structure. The gas adsorption property of SNUT-3 and photocatalytic activity of SNUT-4 for the degradation of Rhodamine B has been explored. [ABSTRACT FROM AUTHOR]

CQDs/ZnIn2S4 (CQDs represents carbon quantum dots) nanocomposites were prepared via a microwave-assisted hydrothermal method. The photocatalytic activity for the reduction of Cr(VI) to Cr(III) over the as-prepared CQDs/ZnIn2S4 nanocomposites under visible light irradiations was studied. The study found that the reduction of Cr(VI) to Cr(III) over hexagonal ZnIn2S4 can be significantly increased by loading CQDs as a co-catalyst. After 60 min of visible light illumination (λ > 420 nm), almost 100% Cr(VI) can convert to Cr(III) with (NH4)2C2O4 as a scavenger. Furthermore, the CQDs/ZnIn2S4 nanocomposites are demonstrated to execute as bifunctional photocatalysts with appreciable activity in the hybrid systems (Cr(VI)/RhB) under visible light, which made it a potential application material for industrial wastewater treatment. Combined with photoelectrochemical analyses, it can be found that the introduction of CQDs can reduce the recombination of photogenerated electron-hole pairs. Finally, a possible photocatalytic reaction mechanism is also proposed. [ABSTRACT FROM AUTHOR]
