The possibility of the participation of dimers of Mg and Zn porphyrins in phototransfer of an electron through the liposome membrane is demonstrated. The authors discovered and investigated two-quantum photoionization of the dimers of some metalloporphyrins (MP) with electron transfer to great distances in glassy concentrated solutions of MP in alcohol matrices in the absence of photoionization of the monomeric molecules. Charge separation in solutions of liposomes sensitized by MP at low temperatures and apparently also at ca 20 degrees C takes place according to a mechanism of two-quantum photoionization of dimeric molecules of the metalloporphyrins.
