分子间氢键棒状手性液晶因其兼具手性液晶奇特的光电性能和氢键液晶的便捷制备以及独特的外界刺激响应性
在功能材料、非线性光学、生物医学等领域具有潜在的应用价值
一直是超分子液晶领域的研究热点。文章按照形成氢键互补基团的不同
将其划分为3种类型
即羧酸-羧酸类、羧酸-吡啶类和其他类型氢键
介绍了此三类氢键棒状手性液晶近年来的研究进展。详细归纳了氢键质子给受体的分子结构、氢键稳定性、手性中心位置、取代基、柔性链长度等对液晶性能的影响
并在此基础上
对其未来发展做了展望。
Due to its unique optical-electro properties
facile synthesis and stimuli responsiveness to the environment
chiral supramolecular liquid crystals based onintermolecularhydrogen bonding have been becoming one of the hot topics in domain of supramolecular chemistry and been winning more application in functional materials
nonlinear optics and biomedical science
etc. This paper presents a brief review on the rod-like hydrogen-bonding chiral liquid crystals (RHCLC). The molecular structure
