Abstract
The quenching of the triplet state of a number of Pd porphyrins and chlorophyll a by other complexes of porphyrins with Pd and Fe in liquid solutions was investigated with the use of pulsed photoexcitation. It is shown that the experimental data are consistent with the results of a kinetic analysis of the mechanism of quenching of the triplet state through the formation of excited complexes of interacting molecules. On the basis of analytical and experimental data, the probability values of intermolecular triplet‐state energy transfer have been determined: K ET = 2·1043·105 sec−1. A conclusion about the character of the excited complexes has been drawn; in particular, the distance between the molecules in the complexes has been estimated to be ∼5 Å.
