Abstract

Abstract: The synthesis of the novel family of heterodinuclear complexes (DP) CoAl (OR)(where DP-is the tetraanion of the diporphyrin biphenylene DPB or the diporphyrin anthracene DPA, and R= CH3, CH2CH,, or CH2C, H5) is reported. These complexes were obtained by selective metalation of the cofacial diporphyrins with cobalt and aluminum. Each (DP) CoAI (OR) complex was characterized by mass spectrometry and UV-vis, IR, ESR, ...
