Polychromophore-catalyst Assemblies

We developed novel approach toward design and synthesis of a polymeric chromophore–catalyst assembly. Chromophore-catalyst assembly is deposited on a semiconductor via the Layer-by-Layer (LbL) self-assembly method to construct a photoanode for photodriven water oxidation applications.
