Figure 1. Synthesis and characterization of FPPs-1. (A) Preparation of FPPs-1; (B) Solid-state 13C NMR spectrum; (C) Solid-state 31P NMR spectrum. Spinning sidebands are marked with asterisks (*); (D) ATR-FTIR spectra; (E-G) fine C 1s, F 1s, and P 2p XPS spectra, respectively. FPPs: Fluorinated phosphine-containing polymers; NMR: nuclear magnetic resonance; ATR-FTIR: attenuated total reflectance Fourier transform infrared.
