Structures and Mesomorphic Properties of Monoarmed Crown Ether Liquid Crystals

Abstract

Abstract: Four monoarmed crown ether liquid crystals were designed and synthesized. The relationship between the properties of liquid crystal and central bridge bond that contact the crown ether and lipophilic structural unit was investigated. The melting point of crown ether liquid crystals was changed a little by variation central bridged bond. The various central bridged bonds change the stability of liquid crystalline phase. The order of clearing point is _N＝CH_ > _N＝N_ > _O_CO_ > _HN_CO_.
