✦ Synopsis

Crosslinked polymers containing pendant tris@ipyridyl)ruthenium(II) complexes [Ru(bipy)$+] were synthesized and examined as sensitizers for the light-induced formation of hydrogen in the heterogeneous system H20/immobilized Ru(bipy):+/ethylenediamine-tetraacetic acid/platinum. Hydrogen generation rates of 0,037 ml/h were obtained with Ru(bipy):+ -complexes immobilized with spacer groups onto hydrophilic carriers based on sucrose-methacrylates as well as hydrophobic carriers based on crosslinked poly(4-aminostyrene), whereas carrier bound complexes without spacer gave lower efficiencies in hydrogen production. The hydrogen generation rates were linear for more than 8 days.
