摘要

Abstract Zinc bis-porphyrin molecular tweezers composed of a N 4 spacer bound through pyridyl units to the meso position of porphyrins were synthesized, and the tweezers are closed by the coordination of a copper (II) ion inside the spacer ligand. The effect of the π–π interaction between the porphyrin rings in the closed conformation on the absorption spectra of multi-electron oxidized species and the reduction potentials were clarified by chemical ...
