Abstract

A PtCl2(bpy) derivative tethered to two viologen (MV2+) moieties drives photochemical H2 evolution via forming a three-electron-reduced species possessing a bpy−˙-based (or MV0-based) reducing equivalent. Such species can only form after one electron reduction of both the MV2+ sites because of rapid intramolecular electron transfer from bpy−˙ to MV2+.
