Self‐Assembled Bilayer Films of Ruthenium(II)/Polypyridyl Complexes through Layer‐by‐Layer Deposition on Nanostructured Metal Oxides

Simple assembly: A “layer-by-layer” deposition of functionalized dyes/catalysts on the surfaces of nanocrystalline oxides is introduced. The strategy is general and offers considerable flexibility based on phosphonate- or carboxylate-binding groups with ZrIV as bridging ions. The resulting bilayer structures are capable of supporting rapid intra-layer energy and electron transfer (see picture).
