Liquid crystal phase transitions under UV irradiation for ether-linked alkoxy azobenzene-triphenylene derivatives

Abstract

Alkoxyazobenzene-triphenylene derivatives with ester linkages are calamitic-discotic bimesomorphic compounds that exhibit both Sm and Col mesophases with molecular shape changes. This phase transition sequence is seen not only by thermal, but also by photonic processes. In this study, the liquid crystal phase transition behavior with ether linkage was investigated
