ABSTRACT Liquid crystalline networks based on compositions of cholesteric siloxanes and low molar mass compounds are studied as components of a liquid crystal nose (LC-nose) that is able to detect a number of volatile organic compounds (VOCs): ethanol, toluene, pyridine, and acetic acid. Selectivity to different VOCs is improved by means of copolymerisation with acrylic acid and blending with low molar mass compound (pentylcyclohexanecarboxylic acid). This modifies the properties of the liquid crystalline matrix by introducing hydrogen donors/acceptors and increases the matrix affinity to certain VOCs. GRAPHICAL ABSTRACT

液晶鼻（LC-nose）：手性网络案例

摘要 基于胆甾醇硅氧烷和低摩尔质量化合物的组合物的液晶网络作为液晶鼻 (LC-nose) 的组成部分进行了研究，该液晶鼻 (LC-nose) 能够检测多种挥发性有机化合物 (VOC)：乙醇、甲苯、吡啶、和醋酸。通过与丙烯酸共聚并与低摩尔质量化合物（戊基环己烷羧酸）混合，提高了对不同 VOC 的选择性。这通过引入氢供体/受体来改变液晶基质的性质，并增加基质对某些 VOC 的亲和力。图形概要
