Crosslinked Nanoparticle Stripes and Hexagonal Networks Obtained via Selective Patterning of Block Copolymer Thin Films

Abstract

Robust arrays of ordered nanoparticles (see Figure and cover) have been created by combining two self-assembly strategies: microphase separation of block copolymers and coordination chemistry. Thin films of a microphase-separated block copolymer serve as templates for patterning of terpyridine-functionalized gold nanoparticles. Subsequent treatment with iron salts crosslinks the patterned nanoparticles via the formation of iron–terpyridine complexes.
