The bottom-up approach to functional nanoscale architectures from molecular components at the surface is the fundamental subject of nanochemistry. Controlling the molecular orientation and alignment on the surface plays an important novel for the surface functionalization. Recently, we have synthesized redox-active Ru/Os complexes bearing tetrapod phosphonate anchors, which acts as not only a electron reservoir but also a linker to bind another molecule units. Using these redox-active Ru/Os complexes as a molecular component, we successfully fabricated a series of multilayer structures with different potential gradient, which can be applied for the functional molecular devices such as photoelectrochemical cells and memory cells. We will also present an electronic conductivity of the molecular ensembles on the surface and the placement of nanomaterials such as DNA and nanoparticles.
