摘要：
Dynamic assembly inclusion complexes of tweezer-type bis(zinc porphyrin) (1) with di(4-pyridyl)porphyrin derivatives have been designed and constructed. The complexes are induced by Zn-N coordination, and the weak binding allows the large-size di(4-pyridyl)porphyrin guests in random rotation. Dynamic characteristics of these assemblies, such as ligand exchange and dynamic fluorescence quenching, have been investigated by H-1 NMR, UV-Vis and fluorescence spectra. The stability of such assembly has pronounced dependence on the size-matching effect and thermal effect.
