3b02 長鎖アルキルアゾベンゼンートリフェニレン誘導体同族列の熱相転移及び光相転移特性(ソフトマター,口頭発表,2012年日本液晶学会討論会)

抄録

The alkyl homologues of azobenzene-triphenylene mesogen(C11-C16) were studied on both thermal and photo-induced phase transitions by DSC, POM and XRD measurements. All homologues exhibit SmA and Colr mesophases and only C12 and C11 possesses SmC phase as the additional mesophase. The clearing points show an odd-even effect. Interestingly, photo intensity dependence on isothermal phase transitions is dependent on the chain length.
