Abstract

The photocatalytic mechanism reported in a recent Communication to produce the radical anion of pyrenes postulates a highly endergonic electron transfer process. An analysis of the thermodynamics is reported together with the proposal of an alternative thermodynamically feasible mechanism.

Keywords: electron transfer; photocatalysis; pyrenes; triplet-triplet annihilation; tris(bipyridine)ruthenium(II).
