纳米材料的手性是一个快速发展的领域，很大程度上是由等离子体、磁性和半导体纳米材料等独特的光学、电子、磁性或催化特性驱动的。液晶在更好地理解其固有的手性光学特性以及作为量化和可视化纳米材料手性的报告剂方面继续发挥着重要作用。此外，液晶相越来越多地被探索作为各种类型纳米材料螺旋组装的潜在可调模板。本综述通过描述纳米材料和液晶手性界面的代表性实例和关键策略，总结了该领域的最新进展。这些研究重点关注一系列尺寸、形状和成分各异的有机和无机纳米材料，以及热致液晶相和溶致液晶相。最后，当液晶分子自组装成能够模板化其他纳米材料的独特丝状手性纳米形状时，这两种材料概念融合在一起。图解摘要
Chirality of nanomaterials is a rapidly evolving field, largely driven by the unique optical, electronic, magnetic or catalytic properties of plasmonic, magnetic and semiconductor nanomaterials among others. Liquid crystals continue to play a major role in developing a better understanding of their inherent chiroptical properties as well as serving as reporters to quantify and visualize nanomaterial chirality. Furthermore, liquid crystal phases are increasingly explored as potentially tuneable templates for the helical assembly of various types of nanomaterials. This review summarizes recent progress in this area by describing representative examples and key strategies pursued to interface nanomaterial and liquid crystal chirality. These studies focus on a range of organic and inorganic nanomaterials varying in size, shape and composition as well as on both thermotropic and lyotropic liquid crystal phases. Finally, the two materials concepts merge when liquid crystal molecules self-assemble into distinct filamentous chiral nanoshapes capable of templating other nanomaterials. GRAPHICAL ABSTRACT
