Abstract
Synthesis of novel fluorinated tetraphenylethene systems 5a-c was carried out and resulting new materials were investigated for their mesomorphic properties. New materials (5a-c) were prepared by the esterification of 3 with either 4-trifluoromethoxybenzoic acid (5a), 3,4,5-trifluorobenzoic acid (5b), or 4- trifluoromethylbenzoic acid (5c). All compounds (5a-c) were fully characterized while stereochemical features of compound 5a were investigated by its single crystal X-ray analysis.
Keywords: tetraphenylethene, mcmurry coupling, liquid crystals
