INVESTIGATION OF THE ENERGETICS OF THE CO VALENTLY-LINKED DEUTEROPORPHYRIN-IX MOLECULAR-SYSTEMS WITH THE QUINONE DERIVATIVES

The energetics of the electronic transitions in the covalently-linked systems of deuteroporphyrin IX with the different p-benzo- and naphtaq uinones derivatives was studied by spectralluminescent and polarograph ic methods. Fluorescent kinetics was reqistrated by the picosecond pul se fluorimeter. The data obtained allow to consider that the reverse e lectron transfer occurs in the studied covalently-linked porphyrin-qui none systems by the absorption of the light quantum and this is the re ason of the substantial fluorescent quenching of the porphyrin.
