We synthesized two thermally-responsive miktoarm star polymers in which poly(Nisopropylacrylamide) (PNIPAM) or poly(oligo(ethylene glycol) methacrylate) (POEGMA) served as the thermosensitive building blocks.The obtained miktoarm star polymers were comprised of a b-CD core, a PEG arm and about six PNIPAM or POEGMA arms. Furthermore, the thermally-responsive behaviors of the miktoarm star polymers were investigated by a combination of UV-vis spectroscopy, DLS, TEM, 1H NMR,
fluorescence spectroscopy and DCS.The architecture of the nano-assemblies formed by PEGCD-PNIPAMx or PEG-CD-POEGMAx was affected by the thermally-induced dehydration of the polymers.
