摘要：A method of immobilizing a catalyst on a substrate surface involves providing

novel ligating copolymers comprising functional groups capable of binding to a substratesurface and functional groups capable of ligating to catalysts such as metal ions, metalcomplexes, nanoparticles, or colloids; applying the ligating copolymer to a substratesurface to cause the ligating copolymer to bind thereto, and contacting the modifiedsubstrate surface with a solution of a catalyst, causing the catalyst to be ligated by theligating copolymer and thus immobilized on the substrate surface. The ligatingcopolymer may be patterned on the substrate surface using a method such asmicrocontact printing. A method of selectively metallizing a substrate in a desiredpattern involves using a ligating chemical agent comprising functional groups capable ofbinding to a substrate surface and functional groups capable of ligating to electrolessplating catalysts; applying the ligating chemical agent to a substrate in a desired patternusing microcontact printing to cause the ligating chemical agent to bind thereto;contacting the modified substrate surface with a solution of an electroless platingcatalyst, causing the catalyst to be ligated by the ligating chemical agent and thus boundto the surface; and metallizing the catalyzed regions of the substrate surface usingelectroless plating.
