Patent ID: 8021753

Claim:
A film having alternating monolayers of a metal-metal bonded complex monolayer and an organic monolayer by layer-by-layer growth, prepared by a process comprising: (1) applying onto a surface of a substrate a first linker compound represented by the formula: G1-Linker a -G2 to produce a primer layer of said first linker compound; wherein G1 is selected from the group consisting of: Cl 3 Si and SH; G2 is selected from the group consisting of: 4-pyridyl 3-pyridyl, cyano, 4-cyanophenyl, 3-cyanophenyl, perfluoro-3-cyanophenyl and perfluoro-4-cyanophenyl: and Linker a is selected from the group consisting of: C 1 -C 8 alkylene, C 1 -C 8 alkenediyl, C 1 -C 8 alkynediyl and 1,4-arylene; (2) applying onto said primer layer a metal-metal bonded complex to produce on said primer layer a metal-metal bonded complex monolayer; wherein said metal-metal bonded complex is selected from the group consisting of compounds represented by the following formulas: and a combination thereof; wherein: L ax is an axial ligand; L eq is an equatorial ligand; wherein two equatorial ligands together form a bidentate ligand wherein each is independently selected from the group consisting of M is a transition metal; wherein the group is a dicarboxylate bridging group selected from the group consisting of compounds represented by the formulas: and mixtures thereof; and wherein m is an integer from 1 to 12, and n is 0 to 3; (3) applying onto said metal-metal bonded complex monolayer a second linker compound selected from the group consisting of: and optionally (4) sequentially repeating steps (2) and (3) at least once to produce said layer-by-layer grown thin film having alternating monolayers of a metal-metal bonded complex monolayer and an organic monolayer.
