NEW POLYMERIZABLE OPTICALLY ACTIVE MATERIAL FROM RAW MATERIAL OF BETA-ESTRADIOL OR METHYLANDROSTENEDIOL, AND OPTICALLY ACTIVE LIQUID CRYSTAL COMPOSITION AND OPTICALLY ACTIVE LIQUID CRYSTAL POLYMER NETWORK CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain the new subject compound capable of being comparatively easily obtained by using β-estradiol or methylandrostenediol as a raw material, having high liquid crystallinity and compatibility, and suitable for an optical element, and a recording and displaying element. ;SOLUTION: This new compound is a polymerizable optically active material of formulas I or II (X is nothing or carbonyl; Y is nothing, a 1-12C alkylene or a 2-12C group having ethylene oxide as a repeating unit; Z is a polymerizable group), or formulas III or IV (W is a group having at least one benzene ring or cyclohexane ring), e.g. a compound of formula V. The compounds of formulas I and III are obtained by introducing substituents containing polymerizable groups to the hydroxy group of the methylandrostenediol. As a result, the objective compound having comparatively large specific rotatory power, and high compatibility with a liquid crystal can be readily synthesized, and various optically functional materials can be provided by using the same.;COPYRIGHT: (C)2000,JPO
