Abstract

The thermochemistry of solution and solvation of meso-substituted porphyrin ligands in three solvents differing in the donor-acceptor properties (benzene, chloroform, dimethylformamide) was studied. The results are correlated with the steric structure of the macrorings. Regular trends in variation of the electronic absorption spectra of the free porphyrins (H2P) and their dications (H4P2+) upon meso substitution were revealed.
