Covalent attachment of fluorescence probes on the PEEK-OH film surface
7-Amino-4-(trifluoromethyl)-coumarin and I-aminopyrene were fixed on the PEEK-OH film surface by direct substitution of the hydroxyl functions in acidic medium. The resulting materials, called PEEK-coumarin and PEEK-pyrene, were analyzed by XPS, ToF-SIMS and fluorescence spectroscopy. This last method was not suitable for quantitative assays.
