Abstract

The irradiation of frozen vitreous solutions of cyanine dyes in the absorption band of the quinoline fragment of the dye molecule leads to the two-quantum phototransfer of an electron from the pigment to the acceptor. The intermediate stages of the charge separation involve the transfer of electronic excitation energy from the quinoline fragment to the dye molecule as a whole. The transfer to the acceptor from a molecule of the dye in the monomeric state is more than 12 times as effective as the transfer of an electron from the dye in an associated state (reckoned for a single molecule in the aggregate.
