Controllable morphology evolution of the copolymers with a pH-switched on/off function. When the thiol–disulfide exchange reaction is activated in the presence of catalytic thiols in pH 12 solutions, the selective core/shell separation gradually leads to the continuous connections of POSS-embedded cores. Then, the self-assembled evolution is performed from unimolecular micelles to form the elliptic nanoparticles. Reprinted with permission from [93].
