Abstract

A newly designed anthryl dendron having perfluoroalkyl chains at terminals showed thermotropic liquid crystallinity, which was characterized using polarizing optical microscopy, differential scanning calorimetry, and X-ray diffraction. The anthryl dendron forms SB phase at room temperature below 53 °C, at which temperature a phase transition to Colrd takes place. In a fluorous solvent, regioselective photodimerization of the anthryl dendron occurred to give head-to-head photodimers, although photodimerization in the SB phase and chloroform gave both head-to-head and head-to-tail photodimers.
