We synthesized pyrene-containing amphiphilic fluorinated copolymers p(C7F15MAA/PyMMA)s through free radical polymerization. The pyrene composition ratio was readily tuned from 0.6 to 3 mol% with different monomer feeding ratios, designated as p(C7F15MAA/PyMMA0.6) and p(C7F15MAA/PyMMA3). p(C7F15MAA/PyMMA) nanoparticle films were prepared by dropcasting copolymer solutions onto substrates with the mixture of AK-225 and acetic acid. The copolymer nanoparticle film surfaces exhibited superhydrophobic character with a water contact angle of greater than 160° and low surface free energy (< 19 mN m−1). The emission from the p(C7F15MAA/PyMMA0.6) nanoparticle film was dominated with monomeric emission, while that from the p(C7F15MAA/PyMMA3) nanoparticle film showed mainly excimer emission. The dissolved oxygen sensing performance of the nanoparticle films was also investigated in terms of the different emission modes.
