66%. The resulting suspension was dialyzed against water for 24h and then characterized by transmission electron microscopy(TEM) and dynamic light scattering (DLS).A series of block copolymers 3−7 showed self-assemblybehavior similar to that of conventional amphiphilic blockcopolymers: as the DP of the sugar-responsive PBOx blockincreased, the morphology of the self-assembled structureschanged from spherical micelles (3, Figure 3A) to cylindrical
