本研究首先通过化学方法将D-HEA连接到聚己内酯的侧链上，然后与Eu（III）配位形成β-二酮大分子配合物，合成了β-二酮基功能化聚合物D-HEA-C。采用1H-1 NMR、FT-IR、GPC、ICP-AES、紫外吸收光谱和荧光发射光谱等方法对D-HEA-C与Eu ~（3+）形成的高分子稀土配合物进行了表征。将合成的β-二酮高分子配合物掺杂到伊娃薄膜中，测试其能量转换效率。采用热重分析、透射率、紫外吸收光谱、荧光发射光谱和扫描电镜对掺杂伊娃薄膜的性能进行了研究。大分子配合物不仅可以限制小分子的配位，有效地避免荧光猝灭，而且可以增强配合物的荧光强度。此外，β-二酮高分子配合物与伊娃基体具有良好的相容性，可提高伊娃薄膜的光电转换效率和使用寿命。因此，β-二酮类高分子配合物可作为高效的光转换分子器件，在太阳能封装薄膜中具有广阔的前景。(C)2014爱思唯尔有限公司版权所有。
In this study, the beta-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 beta-diketones macromolecular complexes. H-1 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 beta-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 beta-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 beta-diketones macromolecular complexes could act as efficient light conversion molecular devices, and have a broad prospect in the solar packaging film. (C) 2014 Elsevier Ltd.
