2b05 オリゴシロキサン鎖を有する液晶性オリゴチオフェンの合成と物性評価(分子配向エレクトロニクス,口頭発表,2012年日本液晶学会討論会)

抄録

We synthesized oligothiophene derivatives bearing oligosiloxane chains at the ends of the alkyl chains. Diphenylterthiophene derivatives having disiloxane chains exhibits high solubility in organic solvents because of the thermal movement of the oligosiloxane chains. On cooling, fibrous structures were formed based on nanosegregation between rigid π-conjugated moieties and flexible oligosiloxane chains. We will also report carrier transport characteristics of the materials.
