Efficient Photoionization of a Norrish II Diradical

摘要

The photochemistry of reactive intermediates in solution is a fascinating subject because of its promise of new mechanisms and applications.Photoionizations of excited singlet and triplet states are common;examples of photoionizations of radicals and radical anions are known.Here,we present the first report on the photoionization of a diradical and show that it is considerably more efficient than that of its precursor triplet.
