摘要
超分子化学是近年来化学界的一个热点,它已在分子识别、分子自组装及分子器件等方面取得了巨大进展。超分子是由两个或两个以上独立的分子亚单位(不同组分)通过不同的键合形式组成。与分立的分子相比,超分子体系中各亚单位在保持其特性的同时又表现出整体效应。利用超分子体系的这种特性,可以方便地构造同时具有分子识别功能和信号表达能力的超分子识别体系。本文综述了几种超分子识别体系的作用机理及其在光化学传感器方面的应用。
Supramolecular chemistry is a very rapidly developed area. It has made great progress in molecular recognition, molecular self-assembly and molecular devices et al. Supramolecular structures are formed by the aggregation of molecules (so called 'molecular subunits'), so they not only have the functions of 'molecular subunits', but also have new functions because of Supramolecular structures. It is useful to construct Supramolecular recognition systems which have the function of molecular recognition as well as information conversion. Here we reviewed several kinds of Supramolecular recognition systems and their applications in optical chemical sensors resently.
