Effect of Molecular Symmetry on the Self-Assembly Behavior of AB2 Linear–Branched Block Copolymers

The architecture of a block copolymer plays a pivotal role in tailoring its self-assembly behavior. In this work, discrete AB2 linear–branched block copolymer isomers with identical chemical structures but varying molecular symmetry were prepared and studied. Comparing to AB linear diblock copolymers, linear–branched AB2 counterparts exhibit significantly different assembly behaviors, which can be further regulated by adjusting the relative …
