芳环上氟原子对手性液晶分子扭曲力的影响
Influence of Fluorine Atom Attached to Aromatic Ring on Heliex Twisting Power of Chiral Liqiud Crystals
摘要
Abstract
A series of chiral liquid crystals were synthesized through Mitsunobu reaction and the yields varied from 63％ to 71％.The compounds were characterized by IR, 1H NMR, MS.The mesomorphic property of objective compounds was investigated by DSC and POM.The helical twisting power (HTP) was determined by Cano's wedge method.It was found that HTP increased with the increase of the number of Fluorine atom attached to aromatic ring.The inducing of fluorine atom to aromatic ring influence the rotation of C-O bond， then chiral moleculer has small number of conformation and exhibits high HTP.关键词
