摘要：

The excited singlet of the 2,4,6-triphenylpyrylium ion (TPP+) reacts with iodobenzene (PhI) by electron transfer leading to radicals and the triplet state of TPP+. The induced formation of (TPP+)-T-3 by spin-orbit coupling has been observed. An encounter complex intermediate is proposed for the quenching of (TPP+*)-T-3 by PhI. Homogeneous recombination of radicals is also observed in the millisecond time domain. Flash photolysis has been used to study the excited state reactions of TPP+.
