This paper briefly introduced the definition, concept, generation and application of supramolecular chemistry. Emphases were put on three parts:① synthesis and self-assembly of new supramolecular compounds;② synthesis and selective recognition effects of new supramolecular compounds;③synthesis and application of su-pramolecular crown ether metal complexes.%简要介绍了超分子化学的定义、概念、产生及应用，详细介绍了：①新型超分子化合物合成及自组装；②新型超分子化合物的合成及选择性识别作用；③超分子冠醚金属配合物的合成及应用。
