we have successfully prepared a series of amphiphilic hyperbranched multiarm copolymer PEHO-starPEOs, which possess different DB in PEHO core. The copolymers can self-assemble into vesicles, wormlike micelles, and spherical micelles with the decrease in the DB, respectively. The findings will contribute to new fundamental understanding in the
relationship between the molecular structures and the self-assemblies of HBPs. Intuitively, amphiphilic hyperbranched multiarm copolymers tend to form unimolecular micelles or fibers. However, hitherto, many delicate supramolecular structures have been reported from the self-assembly of amphiphilic HBPs. Evidently, there are some specialties in the self-assembly of HBPs to afford the morphological complexity, and the DB dependence
may be the most important one among them.
