| titleOfInvention | Dibromo monomer and preparation method thereof, water-soluble random copolymer and preparation method thereof, and fluorescent sensor |
| abstract | The invention belongs to the technical field of chemical analysis and detection, and particularly relates to a dibromo-monomer containing 4, 5-diazafluorene and a preparation method thereof, a water-soluble random copolymer and a preparation method thereof, and a fluorescent sensor. The preparation method of the water-soluble random copolymer comprises the following steps: 1) under the protection of argon, adding a dibromo compound containing 4, 5-diazafluorene groups, 1, 4-dibromo-2, 5-di (3-propoxysulfo sodium sulfonate) benzene and p-phenylboronic acid into an organic solvent according to a molar ratio; 2) and adding a catalyst, heating for reaction, cooling, adding excessive methanol for dissolution, filtering to obtain a solid phase, and purifying the solid phase to obtain the water-soluble random conjugated polymer. The water-soluble random conjugated polymer provided by the invention has excellent water solubility; production of Fe therefrom 3+ The fluorescence chemical sensor has high selectivity. Highly selective recognition of Fe by fluorescence quenching phenomena 3+ And the method is not interfered by common metal ions. |
