Abstract

Four metalloporphyrin dimers linked by bridging amide-bonded xanthene moieties and that contain either Mn^III , Co^II , Ni^II , or Cu^II metal centers were synthesized. Various spectroscopic, electrochemical, and spectroelectrochemical methods were used to study trends in their properties. Their electronic structure and optical properties were analyzed through a comparison of the electronic absorption and magnetic circular dichroism (MCD) spectral data with the results of time-dependent (TD)-DFT calculations.

Keywords: amides; density functional calculations; electrochemistry; heterocycles; porphyrinoids.
