  • The synthesis and electro-optic properties of liquid crystalline 2-(2,3-difluorobiphenyl-4′-yl)-1,3-dioxanes
    作者:Chu Chuan Dong、Peter Styring、John W. Goodby、Lawrence K. M. Chan
    DOI:10.1039/a902351h
    日期:——
    Fifty-six novel alkyl and/or alkoxy disubstituted 2-(2,3-difluorobiphenyl-4′-yl)-1,3-dioxanes (DFBPD) were prepared. Smectic C and nematic mesophases were exhibited by most of the alkyl-alkoxy homologues. Conversely, most of the dialkyl compounds exhibited smectic C, smectic A and nematic phases. The birefringence (Δn), dielectric anisotropy (Δε), spontaneous polarisation and response times of two ferroelectric mixtures formulated from the dioxanyl systems were determined. The birefringence results were compared with eight other groups of mixtures where the materials were based on different core systems. The overall electro-optic properties of the DFBPDs were found to be comparable to the best of the eight most commonly used materials in ferroelectric display devices.
    制备了 56 种新型烷基和/或烷氧基二取代的 2-(2,3-二氟联苯-4´-基)-1,3-二氧六环 (DFBPD)。大多数烷基-烷氧基同系物展现出近晶 C 和向列相中間相。相反,多数二烷基化合物展现出近晶 C、近晶 A 和向列相。测定了两个由二氧六环体系构成的铁电混合物的双折射 (Δn)、介电各向异性 (Δε)、自发极化和响应时间。双折射结果与基于不同核心体系的 8 组混合物进行了比较。发现 DFBPD 的整体电光性质与最常用的 8 种铁电显示器材料相当。
