Abstract

The spectral and kinetic behaviors of radical cations produced under efficient electron- transfer quenching of 1, 4-dicyanonaphthalene or 9, lO-dicyanoanthracene singlet by a number of 2 (3H)-furanones and bis (benzofuranones) have been examined by nanosecond laser flash photolysis (337.1 and 425 nm). The efficiencies of net electron transfer in the course of quenching processes are moderately high (0.2-0.6) in acetonitrile. The radical ...
