Spectral, Acid, and Coordination Properties of Dodecasubstituted Porphyrins

Abstract

The results of investigation of the interrelation between the geometric structure and coordination, acid, and spectral properties of a series of porphyrins with different systems of meso and β substituents are presented. The geometry of polysubstituted porphyrins was optimized at the DFT B3LYP/6-311G level of theory using Gaussian 09. It was shown that the dianionic forms of dodecasubstituted porphyrins hold promise for the development of highly efficient liquid sensors for metal cations.
