EVA film doped with β-diketones macromolecular lanthanide complexes: Preparation, characterization and application
چکیده انگلیسی


• Macromolecular ligand could limit small molecules and enhance fluorescence intensity.
• The complexes were doped into EVA film to enhance the energy conversion efficiency.
• The macromolecular complexes have good compatibility with the EVA matrix.
• The photoelectric conversion efficiency of doped the complexes EVA film was improved.

In this study, the β-diketones groups functionalized polymer D-HEA-C was first synthesized by chemically attaching D-HEA to the side chains of polycaprolactone and then coordinated with Eu(III) to form β-diketones macromolecular complexes. 1H NMR, FT-IR, GPC, ICP-AES, ultraviolet absorption and florescence emission were used to characterize the polymeric rare earth complex materials composed of D-HEA-C and Eu3+ ion. The synthesized β-diketones macromolecular complexes were doped into EVA film to test the energy conversion efficiency. TGA, Transmittance, UV absorption spectra, florescence emission and SEM were used to study the properties of the doped EVA film. The macromolecular complexes could not only limit the coordination of small molecules to effectively avoid the fluorescence quenching, but also enhance the fluorescence intensity of the complex. Moreover, the β-diketones macromolecular complexes have good compatibility with the EVA matrix, and could increase the photovoltaic conversion efficiency and service life of EVA film. Therefore, the β-diketones macromolecular complexes could act as efficient light conversion molecular devices, and have a broad prospect in the solar packaging film.
