A new strategy for constructing helical nanowires via polymerization-induced self-assembly (PISA) mediated by a fluorinated stabilizer block has been developed in this work. Ultralong nanowires with helical structure can be readily produced in a wide range of block compositions. The generality of this strategy was well testified by expanding monomer types, showing a morphology transition from spheres to helical nanowires during aging of achiral BCP nano-objects.
While reliable strategies for constructing block copolymer (BCP) nanowires have been developed, helical nanowires are rarely reported in polymerization-induced self-assembly (PISA). Herein, in this work, a new strategy for constructing helical nanowires was developed via PISA mediated by a fluorinated stabilizer block. Ultralong nanowires with helical structure can be readily produced in a wide range of block compositions. In addition, the generality of this strategy was well testified by expanding monomer types. The achiral BCP nano-objects underwent a morphology transition from spheres to helical nanowires during aging. We believe this work will provide a general strategy for producing helical nanowires through PISA of achiral BCPs.
