A method of immobilizing a catalyst on a substrate surface involves
providing novel ligating copolymers comprising functional groups capable
of binding to a substrate surface and functional groups capable of
ligating to catalysts such as metal ions, metal complexes, nanoparticles,
or colloids; applying the ligating copolymer to a substrate surface to
cause the ligating copolymer to bind thereto, and contacting the modified
substrate surface with a solution of a catalyst, causing the catalyst to
be ligated by the ligating copolymer and thus immobilized on the
substrate surface. The ligating copolymer may be patterned on the
substrate surface using a method such as microcontact printing. A method
of selectively metallizing a substrate in a desired pattern involves
using a ligating chemical agent comprising functional groups capable of
binding to a substrate surface and functional groups capable of ligating
to electroless plating catalysts; applying the ligating chemical agent to
a substrate in a desired pattern using microcontact printing to cause the
ligating chemical agent to bind thereto; contacting the modified
substrate surface with a solution of an electroless plating catalyst,
causing the catalyst to be ligated by the ligating chemical agent and
thus bound to the surface; and metallizing the catalyzed regions of the
substrate surface using electroless plating.
