| Abstract: | 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 1H NMR, UV‐Vis and fluorescence spectra. The stability of such assembly has pronounced dependence on the size‐matching effect and thermal effect. |
