Patterned polymer brushes on carboxyl‐terminated self‐assembled monolayers, and patterned graft/block copolymer brushes on carboxyl‐ containing polymer brush layers, are fabricated. In situ hydrogen‐bond formation between the hydrolyzed trichloro species of the initiator molecules and the COOH–functionalized surface yields the patterned, surface‐confined initiator, and the pattern is amplified into a polymer brush by atom transfer radical polymerization.
