Abstract
The excited singlet of the 2,4,6-triphenylpyrylium ion (TPP+) reacts w ith iodobenzene (PhI) by electron transfer leading to radicals and the triplet state of TPP+. The induced formation of (TPP+)-T-3 by spin-or bit coupling has been observed. An encounter complex intermediate is p roposed for the quenching of (TPP+)-T-3 by PhI. Homogeneous recombina tion of radicals is also observed in the millisecond time domain. Flas h photolysis has been used to study the excited state reactions of TPP +.
