Ligand-regulated Self-Assembly of Luminescent Au Nanoparticles Towards Diverse Controllable Superstructures

Only using one type of amphiphilic block copolymers as a template, we present a facile and robust approach to in situ fabricate a series of brightly emitting Au nano-assemblies with high controllability and tunability. Simply by altering thiol ligands, the Au nano-assemblies display diverse superstructures including fibers, vesicles, and honeycombs.
