Synthesis of novel phthalazinone-based and high-fluorinated poly(arylene ether-1,3,4-oxadiazole)s for selective detection of fluoride

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 gl...
