A number of dendrons of various chain lengths derived from the esters of 3,4,5-tris(tetradecyloxy)benzoic acid were synthesized. These esters were used as building blocks in the design of polyester molecules. Intermediate products, such as branched compou

Two series of novel polycatenar dyes consisting of a triazole azobenzene core were synthesized efficiently by copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. These compounds can self-assemble into SmC and Colhex/p6mm liquid-crystalline phases, and form multistimuli responsive organogels. Bicontinuous cubic phase (CubV) could be induced in the binary system of a bicatenar compound with SmC phase and a hexacatenar compound with Colhex/p6mm phase. Photophysical investigation indicates that these compounds have reversible photoresponsive properties in solution, liquid-crystalline and gel states. They can also act as chemosensors of Fe3+ and sodium dithionite with high selectivity.
Synthesis and liquid crystalline properties of novel fluorinated N-benzoyl thiourea compounds. Effect of perfluoroalkyl chains on the thermal behavior and smectic phases stability

A series of novel N-benzoyl-N’-aryl thiourea derivatives (BTU) bearing different number of alkoxy groups in terminal positions of benzoyl unit and a perfluorooctyl group on the other side have been designed and prepared. Their liquid crystalline properties were investigated by a combination of three techniques: polarizing optical microscopy (POM), differential scanning calorimetry (DSC) and variable-temperature powder X-ray diffraction (XRD). Their thermal stability was studied by thermogravimetric analysis (TG). It was found that only the compounds which have only one alkoxy chain attached to benzoyl unit, 1a and 1b, show calamitic mesomorphic behavior, with smectic A and C phases being displayed. The type and stability of these mesophases are greatly influenced by the alkyl chain length as well as by the presence of perfluorooctyl group. The clearing and the mesophase ranges are significantly increased with the incorporation of perfluoroalkyl chains when compared to non-fluorinated analogues, with almost 40 °C. The attachment of additional alkoxy groups on the benzoyl moiety led to a significant decrease of the clearing points and suppression of the mesogenic character.
