3a04 双連結型キュービック液晶化合物の相転移挙動の赤外分光法による解析(フォトニック・光デバイス/ソフトマター,口頭発表,2013年日本液晶学会討論会)

抄録

Thermotropic hydrogen-bonded cubic mesogens, 4〓31-n-alkoxy-3〓31-nitrobiphenyl-4-carboxylic acid (ANBC-n, where n is the number of carbon atoms in the alkyl chain) and 1,2-bis(4〓31-n-alkoxybenzoyl)hydrazine (BABH-n), supramolecularly organize into two types of bicontinuous cubic (Ia3d and Im3m types) and smectic phases. In the present work, changes in the intermolecular interactions at each portion, i. e. flexible alkyl and rigid core parts, in these compounds at the phase transitions were directly measured using the temperature-variable FT-IR measurement.
