四正电荷环蕃类（Tetracationic cyclophanes）大环化合物是超分子化学中非常经典的具有pai-缺电子芳香结构的环状主体分子之一，在极性溶剂中主要通过pai-给受体相互作用对pai-富电子芳香化合物产生键合作用。本项目以四正电荷环蕃为主要研究对象，并选取了包括一系列特殊的稠环芳香化合物作为客体分子，采用多种分析方法研究对环蕃主体分子与客体分子之间的键合作用，以此来揭示这类键合作用的选择性。这一研究的最终目标是实现对特定稠环芳香化合物的选择性键合，为检测环境非友好的芳香物质以及超分子有机光电子学等领域具有应用前景的高效分子受体提供理论基础和技术支持。

Tetracationic cyclophanes are very classical macrocyclic molecules in supramolecular chemistry which contain extendied pai-electron-deficient aromatic structures. Tetracationic cyclophanes can associate with pai-electron-effient aromatic mlolecular in polar sovents mainly by means of pai-donor-acceptor interaction. This program select tetracationic cyclophanes as the research object, and a serize of specific condensed aromatic compounds as guest molecules. The molecular association between cyclophanes and aromatcs guests were investigated by various testing methods to find out the principle of molecular recognition selectivities.The ultimate purpose of this program is to implement the selective binding and recognition of specified aromiatic compouns, which would theoretically and technically serve to the potential application for the detection of environmentally unfriendly aromatic compounds and supramolecular organic optoelectronic materials.
