中文摘要a novel conjugated polymer (cp) based thin film sensor toward fe3+ was prepared by covalent immobilization of a phosphonate-functionalized polyfluorene on glass surface. contact angle, xps and steady-state fluorescence measurements proved that the polyfluorene was successfully chemically conjugated on the substrate surface. like the organic solution and spin-casting film of this polyfluorene, the fluorescence of the immobilized film can be selectively quenched by fe3+ in both organic and aqueous solutions. limit of detection of this film sensor for fe3+ could be down to 8.4 ppb in thf solution and 0.14 ppm in aqueous solution, which were among the best results for fe3+ sensing by fluorescence film sensors reported so far. compared with the fluorescence quenching properties of the same polyfluorene in thf solution and in spin-casting film, both quenching constant and detection limit of the immobilized film were improved by i order of magnitude, which demonstrated the advantage of the immobilized film fluorescence sensor. in addition, the sensing process is reversible in both organic and aqueous solutions.
