Abstract

Novel azotolane derivatives containing an oligooxyethylene moiety have been synthesized via palladium-catalyzed cross coupling reactions as the key step. The thermotoropic liquid crystalline behavior of the compound was investigated by polarizing optical microscopy and differential scatering calorimetry. Furthermore, we observed that the compound shows trans-cis photoisomerization behavior upon irradiation of ultraviolet light, as well as a conventional azobenzene moiety.
