A new type of liquid crystalline side chain polysiloxane has been built through self-assembly via intermolecular hydrogen bonding between H-bond donor and acceptor moieties. Poly(methylsiloxanes) and poly(methyl-co-dimethylsiloxanes) with side chains containing 4-alkoxybenzoic acid pendant groups attached through aliphatic spacers were synthesized for use as H-bond donor polymers. trans-4[(4-Metho
通过氢键供体和受体部分之间的分子间氢键自组装构建了一种新型液晶侧链聚硅氧烷。聚(甲基硅氧烷)和聚(甲基-共聚-二甲基硅氧烷)的侧链含有通过脂肪族间隔连接的 4-烷氧基苯甲酸侧链,被合成用作 H 键供体聚合物。trans-4[(4-Methoxybenzoyl)oxy]-4'-stilbazole 和 trans-4-ethoxy-4'-stilbazole 分别制备为代表性的介晶或非介晶 H 键受体
