2a05 π共役系色素ドープ液晶の非線形光学的分子配向挙動(ディスプレイ/フォトニクス・光デバイス,口頭発表,2013年日本液晶学会討論会)

π-Conjugated liquid-crystalline (LC) system has attracted as not only optical materials but also next generation of organic electronic materials. It is a key issue to control of molecular alignment for developing optical and electronic devices. LC molecules are known to reorient parallel to the polarization of irradiated light in the field of nonlinear opitcs. In this study, alignment changes in LC system doped with several π-conjugated dyes were induced by a single Ar^+ laser beam. LCs containing coumarin derivatives with high dichroic ratio exhibited photoalignment behavior.
