论文摘要
建议并研究新型液体晶体（LC）组成，并将其作为LC鼻子的元素进行研究。这允许光学检测几种挥发性有机化合物（VOC）。乙醇，甲苯，吡啶和乙酸是通过比色和光谱技术在LC-鼻子手性元素内部扩散过程中检测到的。通过具有不同粘度，对溶剂的亲和力以及形成氢键的能力，通过液晶基质的组成部分来增强对不同VOC的选择性。
Novel liquid crystalline (LC) compositions are suggested and studied as elements of LC-nose. This allows for optical detection of several volatile organic compounds (VOCs). Ethanol, toluene, pyridine and acetic acid were detected by means of colorimetric and spectroscopic techniques during their diffusion inside chiral elements of LC-nose. Selectivity to different VOCs is enhanced by means of components of liquid crystal matrix with different viscosity, affinities to the solvents, and abilities to form hydrogen bonding.
