Abstract

Mono- and adjacent-pyrrole disubstituted porphin dianions (substituents either formyl or vinyl groups) are examined with a semi-empirical SCF MO formalism (CNDO π SCF PSDCI) which includes extensive single and double CI. Calculations predict that the presence of the second conjugating group on an adjacent pyrrole ring enhances the asymmetry introduced by the first group and that the magnitude and orientation of the transition-dipole moments are strongly dependent on the substituent groups.
