A heterografted block copolymer with doubly thermoresponsive grafts is designed to address the challenge in hierarchical self-assembly. Upon heating, solvent isotope dependent morphology transitions from spheres to nanobowls, vesicles, disks, nanosheets, nanoribbons and hyperbranched micelles can be achieved. The strategy provides a general platform to prepare diverse thermoreversible nano-objects.
