Abstract

By using a cosolvent self-assembly approach, the emission of multi-micelle aggregates from star copolymer unimolecular micelles is enhanced greatly through restriction of concentration self-quenching and intermolecular aggregation of a conjugated polymer core, due to the existence of a PEG shell of HCP-star-PEG unimolecular micelles.
