摘要

通过分子间弱相互作用力组装形成的液晶高分子与一般侧链液晶高分子相比

其介晶基元与聚合物主链搭配选择范围宽

且易于组装制备．因此

将氢键［１

２］

离子键［３

４］等引入液晶高分子制备领域

越来越引起人们的兴趣．目前以吡啶羧基氢键组装成的侧链液晶高分子研究得较多［２

３

５］

但由于羧酸本身二缔合体键能约为一般氢键的两倍

拆开二缔合体形成吡啶羧酸氢键难度较高

且在组装需要的较高温下易发生副?...

Abstract

The side chain liquid crystalline polymers were prepared by a self assembly process using 4 (4' nitrophenylazo) phenol or 4 (4' methoxyphenylazo) phenol as hydrogen bond donors and poly(4 vinylpyridine co butyl acrylate) as the acceptor.The hydrogen bond association was confirmed by FTIR.While some dissociation occurs at the isotropic temperature

the complete dissociation needed much higher temperature.The hydrogen bonding was restored as the complex was cooled to room temperature again.The nematic liquid crystallinity of the polymer complex was shown by WXRF and FOM.
