Photogeneration of Hydrogen from Polymeric Viologen Systems

P. C. Lee, Max S. Matheson, Dan Meisel

Open publisher page 20 citations

Abstract

Abstract Polymers containing pendant viologen groups were prepared and studied for their quenching efficiencies of the Ru(bpy)2+3excited state, their back reactions following the quenching, their viologen radical yields, and finally for their effectiveness in hydrogen production in the presence of colloidal platinum. Results are compared with those from methyl viologen containing systems to evaluate the performance of the polymeric viologen systems.
