Abstract
Novel antenna polymers characterized by a polymeric background of a biodegradable water soluble polymer and chromophores chemically bonded to the polymeric background have been found to be useful as photocatalysts in aqueous media. On completion of the desired photochemical reaction, the residual medium can safely be discharged to the natural environment as the catalyst residues undergo biodegradation to form environmentally harmless products.
