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.
