- W1998045987 abstract "A novel fluorene-based copolymer P1 with diphenyl urea as pendent group, as well as its analogous copolymer P2 without urea group for comparison, were synthesized by Suzuki-coupling reaction, and characterized by 1H NMR, EA, IR and GPC. The polymers were brightly blue emissive in THF, DMF, or DMSO solution. Anion titration experiments carried out in THF indicate that the polymer P1 has good selectivity for fluoride ion, acetate ion, and dihydrogen phosphate ion, and the sensitivity and selectivity of P1 toward these anions come from the strong hydrogen-bond interaction between the anions and the urea group of the copolymer. This new system utilizing the strong luminescence property of the polyfluorene as reporter and the hydrogen-bond-forming ability of urea group may act as novel effective anions receptor and chemosensor." @default.
