Abstract:
1. A process for depositing an oxide-free metal-containing film on a surface of a substrate, comprising: a. exposing the surface to a surface-activating agent selected from the group consisting of imines, piperidines, pyrazoles and triazoles to form a deposit of a surface-activating complex on the surface; b. exposing the deposit of the surface-activating complex to a composition consisting of metal precursor to form a deposit of a metal complex on the surface; and c. reacting the deposited metal complex with a reducing agent to form a metal-containing film on the surface, wherein the metal is selected from the group consisting of Co, Ni, Pt, Pd, Ir, and W, wherein the metal precursor is represented by compound (I) wherein m=2, and n=0; M is in the +2 oxidation state and is selected from the group consisting of Co, Ni, Pt, Pd, and Ir; and L is an anionic, bidentate ligand derived from HL represented by Structure (I) wherein m=0 and n=3; M is in the +3 oxidation state and is selected from Co and Ir; L* is an anionic, bidentate ligand derived from HL*, wherein HL* is selected from the group consisting of β-diketimines represented by Structure (II) and N-acetimidoylacetamidines represented by Structure (III) wherein
