Abstract

Cholesteryl S-alkoxybenzene thiocarbonates was synthesized and their liquid crystal transition temperature were determined. Those compounds exhibit enantiotropic cholesteric mesophases. The cholestric-isotropic transition temperatures decrease gradually with increasing alkoxy chain length and mesophase transition were investigated by differential scanning calorimetry.

Cholesteryl S-alkoxybenzene thiocarbonates를 합성하여 그들의 상전이 온도를 조사하였다. 이 계열 화합물들은 모두 호변성 cholesteric 액정상을 나타낸다. 상전이 온도는 시차주사열분석기 (DSC)로 측정하였으며, 측정된 cholesteric-isotropic 상전이 온도는 alkoxy 사슬 길이 증가에 따라 감소한다.
