Abstract
A chiral polymeric micelle is described, formed from the self‐assembly of TPPS and PEG~114~‐b‐P(4VP)~38~ in aqueous media based on their electrostatic interaction. The self‐assembly behavior is studied by DLS, SLS, TEM, UV‐vis absorption spectroscopy, and CD spectroscopy. The experimental results indicate that the resultant hybrid spherical micelles with a hybrid P(4VP)/TPPS core and a PEG shell show chiral signatures. In addition, the chiral micelles have a large dimension and biphasic segregated structure because of the formation of H‐aggregates and J‐aggregates in the micellar core.
