Fluorine-rich block copolymers (BCPs) are applied in a variety of fields ranging from nanomedicine to optics. However, it is difficult to synthesize well-defined fluorine-rich BCPs because blocks bearing long perfluoroalkyl chains have both hydrophobicity and lyophobicity, resulting in their severe lack of solubility. Herein, we report the synthesis and self-assembly behavior of fluorine-rich BCPs prepared from norbornene monomers bearing perfluoroalkyl chains through the controlled ring-opening metathesis polymerization (ROMP) and their micelle formation. Due to the low solubility of the fluorine-rich blocks, the BCPs undergo in-situ self-assembly or micellization during polymerization, the morphology of which can be further modified by the introduction of small volume fractions of fluorous solvents. |
