Surface supramolecular layer-by-layer(LbL) assembly is a promising bottom-up approach to fabricate well-defined
nanostructures on surface. Our group has devoted a lot of effort to develop surface coordination chemistry toward
molecular devices. Starting from the primer layer on the surface, successive coordination of redox- or photoactive
molecular units leads to functional LbL multilayer films with different sequences on the surface, which are relevant to
the surface metal-organic frameworks or networks. In this lecture, I will present (a) sequential LbL fabrication of
redox-active films and their electrochemical and photoelectrochemical behaviors from the viewpoint of molecular
devices such as switches and memories., and (b) alignment of the molecular axis in dinuclear Ru complexes on 1D
single-wall carbon nanotubes.
