  Mixed cellulose-derived benzoates bonded on allylsilica gel as HPLC chiral stationary phases: influence of the introduction of an aromatic moiety in the fixation substituent

  摘要：

  Several mixed alkenoxybenzoyl/benzoates and 10-undecenoyl/benzoates of cellulose were fixed onto allylsilica gel by the radical coupling of double bonds. The introduction of an aromatic group in the fixation substituent modifies the chiral recognition ability of the resulting chiral stationary phases (CSPs) in comparison with the 10-undecenoate/benzoate cellulose derivatives. Better enantioselectivity values are achieved when the electronic and geometric characteristics of both substituents, fixating and derivatizing, are similar. (C) 2003 Elsevier Science Ltd.

  A liquid crystal composition, comprising a main chain-type mesomorphic polymer and a mesomorphic monomer and showing a smectic phase including a plurality of molecular layers, wherein a linkage of a covalent bond is present between adjacent molecular layers among the plurality molecular layers. Because of the presence of the covalent bond linkage between the molecular layers, the elastic energy of the liquid crystal per se relating to the elastic energy between the smectic liquid crystal molecular layers can be controlled to provide a uniform alignment. The mesomorphic polymer preferably has a structure represented by the following formula (1): ##STR1## wherein A denotes a terminal flexible chain group, M denotes a mesogen group, F denotes a spacer flexible chain group, x is 0 or 1, B denotes an ester bond group, ether bond group, thioester bond group, dimethylsiloxane bond group or thioether bond group, and y is 1-200.

  一种液晶组合物，包括主链型向列相聚合物和向列相单体，显示出包括多个分子层的液晶相，其中在多个分子层之间存在共价键的连接。由于分子层之间存在共价键连接，液晶本身的弹性能量与向列相液晶分子层之间的弹性能量有关，可以被控制以提供均匀的排列。向列相聚合物优选具有以下式（1）所表示的结构：##STR1## 其中A表示末端柔性链基，M表示向列相基团，F表示间隔柔性链基，x为0或1，B表示酯键基团、醚键基团、硫酯键基团、二甲基硅氧烷键基团或硫醚键基团，y为1-200。
