A Novel Star-Shaped Zinc Porphyrin Cored [5]Rotaxane
摘要:
A novel star-shaped zinc porphyrin cored [5]rotaxane with four rotaxane arms was synthesized and well characterized by H-1, C-13 NMR spectroscopy and HR-ESI mass spectrometry. The introduction of the zinc porphyrin core enabled the [5]rotaxane to have a fixed shape and symmetrical structure, and the simultaneous shuttling motion of four macrocycles can be driven by external acid-base stimuli. This kind of topological structure exhibits important potential in the design and construction of large sophisticated assemblies.
