Abstract

We used stereolithography to print polymer nanocomposite samples of stimuli-responsive spin crossover materials in the commercial photo-curable printing resins DS3000 and PEGDA-250. The thermomechanical analysis of the SLA-printed objects revealed not only the expected reinforcement of the polymer resins by the introduction of the stiffer SCO particles, but also a significant mechanical damping, as well as a sizeable linear strain around the spin transition temperatures. For the highest accessible loads (ca. 13–15 vol.%) we measured transformation strains in the range of 1.2–1.5%, giving rise to peaks in the coefficient of thermal expansion as high as 10−3 °C−1, which was exploited in 3D printed bilayer actuators to produce bending movement. The results pave the way for integrating these advanced stimuli-responsive composites into mechanical actuators and 4D printing applications.

Abstract

International audience; Macroscopic, soft bilayer spin crossover@polymer actuators were fabricated by a blade casting technique using [Fe(NH2trz)3]SO4 spin crossover particles embedded in a P(VDF-TrFE) matrix. Incorporation of silver flakes in the second layer allowed for electro-thermal actuation via Joule heating. The speed and amplitude of the actuator bending movement, resulting from the expansion/contraction of the spin crossover particles on heating/cooling, were tested for different particle concentrations (15, 25, 33 and 50 wt%) under both open- and closed-loop controls. The capability of the actuators to embark charge and to follow a sinusoidal position was also investigated.

Abstract

International audience; In this paper we report the synthesis and characterization of four novel pentacoordinated diorganotin complexes, obtained through a methodology that involves a multicomponent reaction of 4-([9H-fluorene-2-yl]ethynyl)-2-hydroxybenzaldehyde, 2-amino-5-nitrophenol and diphenyl or dibutyl-tin oxides. Diorganotin complexes 8–11 were obtained in high yields (70–80%) and were fully characterized by solution NMR (1H, 13C and 119Sn), high resolution mass spectrometry (ESI-TOF) and ATR-FTIR. The optical properties were investigated by UV/Vis spectroscopy and Two-Photon Excitation Fluorescence (TPEF). The One-Photon Absorption (OPA) spectra shows two bands located around 400 and 500 nm, additionally, in the Two-Photon Absorption (TPA) spectra there is one main band located around 750 nm characterized by maximum values of TPA cross section (σTPA) in the range 450–500 GM with a secondary band located at 1000 nm with maximum σTPA values of 70 GM; the maximum brightness was observed for 2,2-Dibutyl-6-aza-1,3-dioxa-11-([9,9-dihexyl-9H-fluorene-2-yl]ethynyl)-16-nitro-2-stanna-[d,h]dibenzocyclononene with a value of 150 GM. A theoretical approach within the framework of DFT was applied to study the electronic transitions, showing that the 500 nm band is mainly associated to a HOMO→LUMO transition, and the band at 400 nm to a HOMO-1→LUMO transition. As main highlights the quantum efficiency of fluorescence of these excited states is as large as 0.43 due to the presence of the tin atom which favors molecular rigidity, these compounds possess TPA responses which are significantly enhanced with respect to related organotin chromophores previously reported.

Abstract

International audience; Boron and tin complexes have been a versatile and very interesting scaffold for the design of nonlinear optical (NLO) chromophores. In this paper we present a wide range of reports since the 1990s to date, which include second-order (e.g., second harmonic generation) and third-order (e.g., two-photon absorption) NLO properties. After a short introduction on the origin of the NLO response in molecules, the different features associated with the introduction of these inorganic motifs in the organic-based NLO materials are discussed: Their effect on the accepting/donating capabilities of the substituents, on the efficiency of the _-conjugated linkage, and on the topology of the chromophores which can be tuned from the first generation of “push-pull” chromophores to more sophisticated two- or three-dimensional architectures.

Abstract

International audience; A ruthenium nitrosyl complex of formula [RuII(terpy)(F2B)(NO)](PF6)3, where terpy stands for 2,2′:6′,2″-terpyridine and F2B for 4,4′-bis(9,9′-dibutyl-9H-fluoren-2-yl)-2,2′-bipyridine, is presented and fully characterized. The X-ray crystal structure of F2B is reported. The electronic properties of the complex are compared to those of related [RuII(terpy)(bpy)(NO)]3+ complexes having a bipyridine (bpy) free of fluorene or bearing a fluorene on the terpyridine ligand. DFT computations are provided to support the experimental data. [RuII(terpy)(F2B)(NO)](PF6)3 releases NO under irradiation at 405 nm with a quantum yield (ϕNO) equal to 0.033. Additionally, the two-photon absorption cross-section investigated at 800 nm by the Z-scan technics is equal to 156 ± 23 GM, which indicates that the complex can release NO under irradiation in the therapeutic window.

Abstract

International audience; A ruthenium–nitrosyl derivative of formula [RuII(CzT)(bipy)(NO)](PF6)3 [CzT = 4′-(N-ethylcarbazol-3-yl)-2,2′:6′,2′′-terpyridine, bipy = 2,2′-bipyridine] has been synthesized and fully characterized, and compared with the previously reported [RuII(FT)(bipy)(NO)](PF6)3 complex [FT = 4′-(9,9-dihexyl-9H-fluoren-2-yl)-2,2′:6′,2′′-terpyridine]. Additionally, the X-ray crystal structure of [RuII(CzT)(bipy)(NO2)](PF6), the precursor of [RuII(CzT)(bipy)(NO)](PF6)3, is reported. The presence of a tertiary amine in the carbazole unit leads to redshifted charge-transfer transitions towards the electron-withdrawing Ru–NO fragment and hence enhanced two-photon absorption (TPA) properties. In contrast, the quantum yield of the NO· photorelease process is lower for the carbazole-containing complex. The issue of optimization of the TPA versus NO·-release capabilities is addressed.

Abstract

International audience; Ru-II(FT)(bipy)(NO)][PF6](3) [FT is the electron-rich 4'-(2-fluorenyl)-2,2': 6',2 ''-terpyridine ligand and bipy is 2,2'-bipyridine] is synthesized and characterized. It crystallizes in the triclinic P (1) over bar space group [a = 9.5362(2) angstrom, b = 10.3946(4) angstrom, c = 22.5701(8) angstrom, alpha = 94.7400(10)degrees, beta = 94.9400(10)angstrom, gamma = 101.0680(10)]. A photochemical study is presented in comparison with that of the parents cis(Cl, Cl)-[RuII(FT) Cl-2(NO)][PF6] and trans(Cl, Cl)-[RuII(FT) Cl-2(NO)][PF6]. The three derivatives release nitric oxide ((NO)-N-center dot) under irradiation at lambda = 405 nm with respective quantum yields of 0.06, 0.31, and 0.10. Their two-photon absorption (TPA) cross-sections (sTPA) were investigated by the Z-scan technique on related derivatives in which two hexyl chains were introduced to improve their solubility while their spectroscopic properties remained almost unaffected. The resulting sTPA values of 100 GM at. = 800 nm are in the window of transparency for human tissues, and the bipyridine-based complex exhibits a slight tendency for higher efficiency. The replacement of the [Ru-II(Cl)(2)(NO)] core by [Ru-II(bipy)(NO)] provides a much simpler synthesis, and the TPA-induced (NO)-N-center dot-release capabilities are in the same range of magnitude. Therefore, it is envisioned that (NO)-N-center dot donors of greater complexity with several metal centers could be investigated in future.
