PHOTOINDUCED TWO-ELECTRON REDUCTION OF METHYL VIOLOGEN DIMER BY 2-PROPANOL THROUGH INTRAMOLECULAR PROCESS AND FORMATION OF VIOLOGEN RADICAL CATION DIMER

Abstract

In the photoreduction of the newly synthesized methyl viologen dimer,1′,1″-trimethylene-bis(1-methyl-4,4′-bipyridinium) perchlorate, by 2-propanol, the exclusive formation of the stable radical cation dimer at room temperature was observed, which gave an unequivocal evidence for the intramolecular process.
