AbstractMulticompartment disks with bumpy edges could be synthesized controllably by dissolving a linear ABC amphiphilic triblock copolymer of polystyrene-b-polybutadiene-b-poly (2-vinylpridine) (PS440-b-PBd1020-b-P2VP114) in selective solvent mixtures of toluene and methanol. The disk size was controllable by the initial copolymer concentration. Diameter of the disks increased with the increase of the copolymer concentration. Interestingly, through adding a homo-PS to the system morphological transition took place from multicompartment disk with bumpy edges to sphere, and to hollow sphere with bumpy surfaces. Furthermore, the diameters of the hollow spheres increased with the increase of the homo-PS content, whereas the diameters of the hollows remained unchanged. Moreover, the PB block could be cross-linked by UV irradiation, stabilizing the preformed structure.

We report the photocontrollable micelle–cluster transition of an ABC-type triblock copolymer in an ionic liquid (IL). Polystyrene-b-poly(ethylene oxide)-b-poly(4-phenylazobenzyl acrylamide-r-N-isopropylacrylamide) (PSt-b-PEO-b-P(AzoBnAm-r-NIPAm)) was synthesised, where PSt is IL-phobic, PEO is IL-philic, and P(AzoBnAm-r-NIPAm) is photo- and thermoresponsive in the IL. At high temperatures, the triblock copolymer forms micelles with PSt cores; furthermore, at low temperatures, micelles self-assemble into clusters induced by the aggregation of P(AzoBnAm-r-NIPAm). Under UV irradiation, the micelles form clusters at lower temperatures than that in the dark because of the change in the solubility of P(AzoBnAm-r-NIPAm) induced by photoisomerisation of the azobenzene groups, indicating that this triblock copolymer has a photocontrollable micelle–cluster transition temperature.
