ロッド状-ディスク状両分子部分からなる液晶性化合物：エーテル基により結合されたアルコキシアゾベンゼン-トリフェニレン誘導体の液晶相転移

抄録

Triphenylene derivatives substituted with six alkoxy-azobenzene units at its surroundings linked by ester groups were found to exhibit bimesomorphic properties of calamitic smectic (Sm) and discotic columnar (Col) mesophases. Furthermore, we have obtained results suggesting that the liquid crystal (LC) phase transition varies greatly depending on flexibility of the linkage group. In this work, the phase transition of two alkyl homologues for the ether-linking derivatives is presented as its detail obtained by synchrotron XRD measurements.
