, p. 3800 - 3807 (2016)
We report the synthesis of phenylene(vinylene) based blue light emitting polymer by atom transfer radical polymerization with very good yield. Their photophysical properties were studied systematically with increasing polarities of solvent and sensing of nitro aromatics in solution and in vapor phase. The sensory properties of the polymer were studied toward various nitroaromatic compounds like nitrobenzene (NB), nitrotoluene (NT), dinitrobenzene (DNB), dinitrotoluene (DNT), nitro benzoic acid (NBA), 3-nitro benzaldehyde (3-NBA), trinitrotoluene (TNT), 4-nitrophenol (NP), and picric acid (PA) in solution state.

The direct bonding between a thiazolo[5,4-d]thiazole and two 1,3,4-oxadiazole units allowed us to create a new and versatile rigid core for luminescent liquid crystal, which showed interesting and variable mesomorphic and photophysical properties. From the 5-bis(5-phenyl-1,3,4-oxadiazol-2-yl)thiazolo[5,4-d]thiazole new core, three molecules with different number of alkoxy chains were synthesized and had their properties correlated with the molecular structure. The molecule with two chains showed a smectic C mesophase, while the mesogens with four and six chains presented hexagonal columnar mesomorphism, which was confirmed by POM and XRD measurements. In addition, the molecule with six chains presented liquid crystalline behavior close to room temperature. In solution, the molecules presented strong photoluminescence ranging from blue to yellow, with quantum yields higher than 0.6. Excited state lifetimes allowed to correlate the fluorescence component associated to the different emitting species to the molecular organization in spin coated films. The molecular energy levels, together with thermal stability and possible charge carrier transport due to molecular packing, suggest that these molecules are promising for optoelectronic applications. Overall, this work contributes to the development of the use of thiazolo[5,4-d]thiazole in liquid crystals, demonstrating its great efficiency and versatility.

Synthesis, characterization and aggregation induced emission properties of anthracene based conjugated molecules

Aggregation induced emission-active branched and linear 9,10-distyrylanthracene derivatives with different length alkoxy chains have been designed, synthesized and the effect of chain length on the solid-state fluorescence properties systematically investigated. All the three anthracene derivatives possess typical aggregation induced emission (AIE) properties, i.e., they exhibit faint emission in their solutions, but intense emission in their aggregate states, as a result of the dominant nonradiative decay of free intramolecular torsion in the solution and also the restricted torsional motion from supramolecular interaction in the solid states. The results show that these materials exhibit not only AIE properties, but also observed were position and chain length dependent fluorescence properties. The shorter alkoxy chains were more red shifted than the longer ones and also different aggregation behaviours for branched and linear molecules were observed. This work demonstrates once again the accessibility of tuning the solid-state optical properties of organic fluorophores by combining the simple alternation of molecular chemical structures and the physical change of aggregate morphology under external stimuli.
