Abstract:
1. A process for preparing a film having alternating monolayers of a metal-metal bonded complex monolayer and an organic monolayer by layer-by-layer growth, said process comprising: (1) applying onto a surface of a substrate a first linker compound represented by the formula:  to produce a primer layer of said first linker compound on said substrate, wherein G1 is a functional group capable of interacting with said surface of said substrate; G2 is a functional group capable of interacting with a metal-metal bonded complex; and Linker (2) applying onto said primer layer a layer of a metal-metal bonded complex to produce a metal-metal bonded complex monolayer on said primer layer; said metal-metal bonded complex being selected from the group consisting of compounds represented by the following formulas: and a combination thereof; wherein: L L M is a transition metal; wherein  is a bridging group each selected independently from the group consisting of: SO (3) applying onto said metal-metal bonded complex monolayer a second linker compound represented by the formula:  to produce on said metal-metal bonded complex monolayer an organic monolayer; wherein G3 and G4 are the same or different functional groups capable of interacting with a metal-metal bonded complex; and Linker (4) sequentially repeating steps (2) and (3) at least once to produce said layer-by-layer grown film having alternating monolayers of a metal-metal complex monolayer and an organic monolayer.
