| titleOfInvention | Water-dispersible hyperbranched conjugated polymer fluorescent nanoparticles as well as preparation method and application thereof |
| abstract | The invention relates to water-dispersible hyperbranched conjugated polymer fluorescent nanoparticles as well as a preparation method and an application thereof and aims to solve the technical problem of low sensitivity of conjugated polymers used currently during detection of nitro-aromatic compounds in a water phase. An internal hydrophobic cavity structure and a terminal hydrophilic structure of each nanoparticle are a hyperbranched conjugated polymer core part composed of conjugated structure units Ar1 and Ar2 and sodium oxypropyl sulfonate or sodium oxybutyl sulfonate generated through a reaction between terminal hydroxyl of precursors of the hyperbranched conjugated polymer fluorescent nanoparticles and 1,3-cyclopropane sultone or 1,4-cyclobutyl sultone respectively. The nanoparticles prepared with the method are effectively combined with TNT molecules through a hydrophobic enrichment function, and the detection sensitivity is remarkably improved. The quenching coefficient and the detection limit of the hyperbranched conjugated polymer fluorescent nanoparticles can be improved by several magnitudes in comparison with traditional linear conjugated polymers and nanoparticles of the traditional linear conjugated polymers, and the selective detection of TNT in an aqueous solution can be realized. |
