For gold NPs capped with end\u2010grafted poly(styrene\u2010block\u2010(4\u2010vinylbenzoic acid)), P(St\u2010block\u20104VBA), block copolymer ligands, surface\u2010pinned micelles (patches) formed from NP\u2010adjacent PSt blocks under reduced solvency conditions (Stimulus\u20051); solvated NP\u2010remote P(4VBA) blocks stabilized the NPs against aggregation. Subsequent self\u2010assembly of patchy NPs was triggered by crosslinking the P(4VBA) blocks with copper(II) ions (Stimulus\u20052). Block copolymer ligand design has a strong effect on NP self\u2010assembly. Small, well\u2010defined clusters assembled from NPs functionalized with ligands with a short P(4VBA) block, while NPs tethered with ligands with a long P(4VBA) block formed large irregularly shaped assemblies. This approach is promising for high\u2010yield fabrication of colloidal molecules and their assemblies with structural and functional complexity.<\/jats:p>","DOI":"10.1002\/anie.201904430","type":"journal-article","created":{"date-parts":[[2019,5,3]],"date-time":"2019-05-03T01:55:01Z","timestamp":1556848501000},"page":"9269-9274","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":61,"title":["Staged
