Progress of Hydrogen-bonded Side-chain Polysiloxane Liquid Crystal

通过与传统的侧链聚硅氧烷液晶的对比,阐述了氢键自组装侧链聚硅氧烷液晶独特的优点;简要介绍了羧基-羧基体系、羧基-吡啶体系、羧基-咪唑体系氢键自组装侧链聚硅氧烷液晶的研究现状,此外,还根据类似的非聚硅氧烷型液晶体系设想了羧基-氨基吡啶体系氢键自组装侧链聚硅氧烷液晶和酚羟基-吡啶体系氢键自组装侧链聚硅氧烷液晶;并概述了液晶常用的表征方法。

Compared with the traditional side-chain polysiloxane liquid crystal,hydrogen bond self-assembly of the side-chain polysiloxane liquid crystal had its own particular advantages.The research progress of hydrogen bond self-assembly of the side-chain polysiloxane with the carboxyl/carboxyl system,carboxyl/pyridine system and carboxyl/imidazole system was reviewed.According to the synthesis of ultra molecular liquid crystal with the organic small molecular unit and side chain polymer liquid crystal system,the design of the carboxyl/aminopyridine and the phenol hydroxyl/pyridine system were proposed.At last,the analysis methods for suparmolecular liquid crystal were also discussed.
