摘要
Lewis pair polymerization has demonstrated its unique advantages and powerful capability in polymer synthesis. Here we employ strong nucleophilic N-heterocyclic olefin (NHO) and bulky organoaluminum to construct a frustrated Lewis pair, which can realize the compounded sequence control (CSC) copolymerization and self-assembly the mixture of dimethylaminoethyl acrylate and fluoride-functionalized methacrylate into diblock copolymers (di-BCPs) nano-assemblies through polymerization-induced self-assembly in one-pot, single-step manner within minutes. These di-BCPs were characterized by 1 H and 13 C NMR, GPC, DSC, and TEM. By utilizing appropriate solvophilic block and solvophobic block, such Lewis pair polymerization-induced self-assembly strategy enables the expeditious, room-temperature synthesis of di-BCP nanoparticles with different morphologies, including spheres, worms, vesicles, and even fibers, thus suggesting the great application potential of such method in the future.
