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 hot spot in chemistry in recent years. It has made tremendous progress in molecular recognition, molecular self-assembly and molecular devices. Supramolecules are composed of two or more independent molecular subunits (different components) through different forms of bonding. In contrast to discrete molecules, each subunit in a supramolecular system exhibits its overall effect while retaining its properties. Using this property of supramolecular system, it is convenient to construct a supramolecular recognition system that has both molecular recognition and signal expression capabilities. This article reviews the mechanism of several supramolecular recognition systems and their applications in photochemical sensors.
