  CdSe/ZnS Nanoparticle Composites with Amine-Functionalized Polyfluorene Derivatives for Polymeric Light-Emitting Diodes: Synthesis, Photophysical Properties, and the Electroluminescent Performance

  摘要：

  A series of amine-functionalized poly(9,9-dihexylfluorene) (PFH) derivatives, PFH-NH2F-39-1 (P1), PFH-NH2F-19-1 (P2), PFH-NH2F-9-1 (P3), and PFH-NH2F-17-3 (P4), and PFH-NH2F-4-1 (P5), were developed to form organic/inorganic hybrid composites with CdSc/ZnS nanoparticle for polymeric light-emitting diodes (LEDs). The structures and purities of all desired polymers were fully characterized by H-1 and C-13 NMR, UV-vis and photoluminescent spectroscopy, gel permeation chromatography, elemental analyses. The hybrid nanocomposites were in situ formed through these amino-functionalized polyfluorene derivatives doped with core-shell CdSe/ZnS quantum dots (QDs). The detailed characterizations of their photophysical properties revealed that rapid Forster energy transfer from the conjugatee polymers to the red-emitting QDs afforded an efficient red color emission. The preliminary polymeric LEDs fabrication with the configuration of ITO/DB/nanocompositcs/Al achieved red emission for the ill Situ prepared hybrid nanocomposites. The investigation of device performance indicates that these nanocomposites are promising red light-emitting polymeric LED materials with good performance in providing excellent color purity, stability, and robustness. Such strategy provides us a platform to achieve red-emitting hybrid nanocomposites as the active materials for LEDs.

  We report a facile grafting-from strategy towards the synthesis of inorganic–organic composites of semiconductor nanocrystals and wide-bandgap polymers. Amino-functional fluorenes have been used as co-ligands for CdSe nanocrystals, thus enabling us to design their surface directly during the synthesis. Highly monodisperse, strongly emitting CdSe nanocrystals have been obtained. Subsequently, a straightforward Yamamoto C–C coupling protocol was used to carry out surface polymerisation, hence modifying CdSe nanocrystals with oligo- and poly(fluorene) moieties. Both amino-fluorene capped CdSe nanocrystals and the resulting nanocrystal–polymer composites were characterized in detail by optical and FT-IR spectroscopy, TEM, AFM, and gel permeation chromatography, showing their potential as novel functional inorganic–organic hybrid materials.

  我们报告了一种简便的嫁接策略，用于合成半导体纳米晶体和宽带隙聚合物的无机-有机复合材料。氨基功能芴已被用作CdSe纳米晶体的共配体，从而使我们能够在合成过程中直接设计其表面。获得了高度单分散、强发射的CdSe纳米晶体。随后，使用直接的山本C-C偶联方案进行表面聚合，从而用寡聚和聚（芴）部分修饰CdSe纳米晶体。通过光学和FT-IR光谱、TEM、AFM和凝胶渗透色谱法对氨基芴封端的CdSe纳米晶体和所得纳米晶体-聚合物复合材料进行了详细表征，表明它们作为新型功能无机-有机杂化材料的潜力。
