能模拟酶的识别和催化性能的分子的设计和合成，正越来越引起化学家的关注。1994年2月，McPartlin等报道了一个超分子系统——锌卟啉环状三聚物的三吡啶加合物（简称加合物1）的X一衍射结构。1993年的研究表明，与很多酶的性能相似，加合物（1）通过增强与底物之间的反应，使其 The design and synthesis of molecules that mimic enzyme recognition and catalytic performance are increasingly attracting the attention of chemists. In February 1994, McPartlin et al. Reported the X-ray diffraction structure of the terpyridine adduct (abbreviated as adduct 1) of a supramolecular system, a porphyrin cyclic trimer. Studies in 1993 showed that, similar to the performance of many enzymes, adduct (1) enhances the reaction with substrate by
