Abstract

A polymer (e.g., a photocatalytic polymer) that contains chromophoric units therein (e.g., covalently coupled therein, in the polymer backbones and/or side chains), is described. In some embodiments, the polymer comprises: (a) a first ligand as a first repeating monomeric unit therein (e.g., as part of the polymer backbones and/or side chains); (b) a transition metal (e.g., Ru, Ir, Fe, Co, etc.) complexed with said first ligand to form a chromophoric unit or transition metal photocatalyst therewith; and (c) optionally but preferably at least one additional ligand (e.g., one or two) complexed with said transition metal to form said chromophoric unit or transition metal photocatalyst; and (d) optionally but preferably a second monomeric unit copolymerized with said first monomeric unit. Compositions containing the same and methods of using the same are also described.
