Abstract

Abstract: The photochemistry of a-terthienyl (aT) and related compounds has been examined in homogeneous solution and in anionic micelles in the presence of electron acceptors. The absorption spectra of the radical cations from four thiophenic substrates have been characterized; for example, those derived from a-bithienyl (aB) and aT show absorption maxima at 420 and 530 nm, respectively. Triplet quenching by acceptors such ...
