Aim To synthesize a series containing phthalazinone new fluorinated poly(phthalazinone ether-1,3,4-oxadiazole): selective detection of fluoride ion. Methods The poly(arylene ether)s were designed, the optimal methods of synthesis were studied by the N-C coupling reaction. Results A class of highly fluorinated poly(phthalazinone ether-1, 3,4-oxadiazole)s were prepared from several phthalazinone containing-monomers 2a-2e. The obtained polymers 3a-3e exhibited good solubility in common organic solvents, high glass transition temperatures in the range of 249～285 ℃ and excellent thermal stability. Moreover, The prepared poly (phthalazinone ether-1, 3,4-oxadiazole) s were found to be capable of selectively binding fluoride ion with high affinity, and displayed new peaks in fluorescence spectra, producing no response to the other tested anions including Cl-, NO3-. Conclusion The feature made them potential candidates for fluoride detection.
