Abstract
A series of oxacalix[4]arene-linked cofacial bisporphyrins 2-4 have been synthesized as free-bases, biszinc(II) and biscopper(II) complexes. UV-vis, fluorescence and cyclic voltammetric studies were performed on the bisporphyrins. Little electronic interactions between the two porphyrin macrocycles in both the metal-free and biszinc(II) complexes 2 and 3 were observed, while enhanced electronic communications were observed in the case of 4 bearing two copper(II) metal ions. Geometry optimizations were carried out using HF/CEP-31G methods to investigate the molecular structures of these bisporphyrins. Solvent effects on the photophysical properties of these bisporphyrins are also discussed. © 2010 World Scientific Publishing Company.
