“…Such columnar organization of hexanuclear clusters remains scarce and has only been observed up to now in ternary polyionic inorganic compound Cs 2 Mo 6 Br 14 and 18-crown-6 ethers bearing two o-terphenyl units. 62 In addition, the association of emissive clusters with conducting stacking stacks of TP should be of great interest for applications in optoelectronic.…”

“…61 Recently, an original supramolecular strategy using discotic crown-ether able to complex the alkali counter cations of the anionic cluster units has been developed to design columnar liquid crystals. 62 Triphenylene (TP) derivatives are archetypical of discotic liquid crystals (DLCs). 59 The large π-conjugated system with high symmetry can easily be functionalized and the grafting of linear alkyl chains from C4 to C11 allows the facile emergence of columnar mesophases of hexagonal symmetry (Col h ).…”

Providing several functionalities to a single material is an emerging challenge with many industrial prospects in materials sciences. Self-assembled organic-inorganic hybrid materials endowed with emission properties are part of these new materials. While the inorganic moieties provide emissivity, the organic part confers nanostructuration and processability. Here we describe how columnar arrangements can be obtained by assembling, via electrostatic interactions, isometric anionic inorganic nanoemitters, namely [Re6Se8(CN)6]4-, with imidazolium counter cations bearing triphenylene units. The resulting hybrids combine the emission of both components and energy transfer has been evidenced between both entities. Hole charge mobilities of the hybrid organic-inorganic columnar mesophases were also evaluated by the space charge limited current (SCLC) method.

“…For instance, with iodine, the substitution via solution chemistry of apical I a by OCOC n F 2n?1 groups leads to Cs 2 Mo 6 I i 8 ðOCOC n F 2nþ1 Þ a 6 (n = 1, 2, 3) series [20,21]. From the viewpoint of optical properties, the Mo 6 [22,23]. Last but not least, the whole series Cs 2 Mo 6 X i 8 X a 6 (X = Cl, Br and I) has been used as precursor for their integration in silica nanoparticles Cs 2 Mo 6 X i 8 X a 6 @SiO 2 [2,3,[24][25][26].…”

International audienceWe report here the synthesis, the crystal structure and the luminescent properties of the new cluster compounds Cs2Mo6Cl14·H2O and Cs2Mo6Br14·H2O. Single-crystal X-ray diffraction performed on Cs2Mo6Cl14·H2O indicates that the compound crystallizes in the monoclinic space group C2/c with refined cell parameters a = 19.578 Å, b = 15.151 Å, c = 9.347 Å, and β = 115.64°. The structure can be described from discrete [Mo6Cl8iCl6a]2- anionic cluster units arranged in a “A–A’–A–A’” pseudo prismatic stacking parallel to (b, c) plane with both Cs+ cations and water molecules located between the layers. Moreover, the centric character of the trigonal structure of Cs2Mo6Cl14 was also studied by combination of single-crystal X-ray diffraction and both X-ray and neutron powder diffraction. The results suggest an important influence of the sample preparation on the symmetry of the crystal structure. The crystal structure relationship between the [Mo6Cl8iCl6a]2- anionic cluster unit arrangements in Cs2Mo6Cl14 and Cs2Mo6Cl14·H2O is discussed. Finally, the characterization of the luminescent properties of Cs2Mo6X14 and Cs2Mo6X14·H2O (X = Cl, Br) indicates that emission profile is comparable regardless existence of water molecule in the crystal structure. © 2016, Springer Science+Business Media New York

“…The inset of Figure (a) shows the red emission of the doped‐PUcc sample taken under a 365 nm irradiation and gives another evidence of the homogeneous integration of nanoclusters in PUcc. Recently, we showed that the nanocluster anion emission behavior toward a temperature modulation could be used to sense the molecular nanostructuration changes within a liquid crystalline hybrid material . Here, we decided to investigate if such ability could also be observed within a polymer matrix.…”

International audienceNew biobased polyurethanes were synthesized from cyclocarbonated broccoli seed oil and different di- or triamines. The isocyanate-free route to synthesize these polyurethanes was divided into three steps: the broccoli seed oil was first epoxydized, then carbonated with CO2 at a pressure of 50 bar to convert oxiranes into cyclic carbonates, and finally polyurethanes were prepared through the reaction of the cyclocarbonated oil with three different di- or triamines, that is, butylene diamine, m-xylene diamine, and bis(hexamethylene triamine). The chemical reactions were monitored by Fourier transform infrared spectroscopy, nuclear magnetic resonance, and electrospray ionisation mass spectrometry and mechanical properties of thus-prepared polyurethanes were determined by dynamic mechanical analysis and tensile characterization. An UV-responsive material was finally prepared from butylene diamine based polyurethane integrating phosphorescent molybdenum nanoclusters. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
