Polymerization-induced Self-Assembly (PISA) is a facile and versatile method for preparation of block polymer nanoparticles at high concentrations. So far, most PISA examples are based on linear diblock copolymer systems and investigation of architecture effect in PISA such as bottlebrush has been largely unexplored. Here, we report synthesis of Janus bottlebrush polymers by combination of grafting-through and grafting-from polymerizations, and PISA behavior in the grafting-from stage. This approach enables evaluating the effect of bottlebrush architecture compared to linear diblock PISA by varying the grafting number, which can be set in the grafting-through step. Synthetic details of the bottlebrush polymers and their self-assembly behavior will be discussed. |
