合成了一种含柔性间苯键的大环二吡咯四聚体及其四核锌配合物。由于大环骨架的构象灵活性，所得配合物具有不对称的8字形结构。第一个μ-羟基-和μ-乙酰基-桥接的双核锌（II）二吡咯配合物结构是在扭曲的大环配合物中实现的。此外，配合物在甲苯和氯仿中表现出有效的发射。
A macrocyclic dipyrrin tetramer containing flexible m-phenylene linkages and its tetranuclear zinc(II) complex were synthesized. The obtained complex has an unsymmetrical figure-of-eight structure because of the conformational flexibility of the macrocyclic framework. The first mu-hydroxo- and mu-acetato-bridged dinuclear zinc(II) dipyrrin complex structure is realized in the twisted macrocyclic complex. Furthermore, the complex exhibited an efficient emission in toluene and chloroform.
