Abstract

Photochromic liquid crystals based on [2H]-chromenes functionalised in the 3,3[prime or minute]-positions by phenyl groups linked to 4-cyano-4[prime or minute]-hydroxybiphenyl groups via alkyl and siloxane spacers as chromophore were synthesised and the photochromic and mesomorphic behaviour was investigated.

摘要

合成了基于[2H]-色烯的光致变色液晶，其在3,3'-位通过烷基和硅氧烷基间隔基与4-氰基-4'-羟基联苯基团相连的苯基进行官能化，作为发色团，并研究了其光致变色和介晶行为。
