  具有非共轭三苯胺基核的 3D 单分散低聚芴：合成和光电特性

  摘要：

  通过 Friedel-Crafts 共缩聚反应合成了两种具有非共轭三苯胺基核的 3D 单分散低聚芴。低聚物PF 3 -TPA 和PF 3 -TPA 3 由三个芴五聚体臂组成，它们通过三苯胺（TPA）和1,3,5-三（三苯氨基）苯核（TPA 3 ）非共轭连接，分别位于五芴臂中心芴的 9 位。核的共面结构和五芴臂中心的连接产生了低聚物的 3D 结构。这种特殊的结构有效地延缓了五芴臂的结晶趋势，并使材料完全无定形的形态结构。两种低聚物都在薄膜中发出高效率的深蓝色荧光（Φ pl-film = PF 3 -TPA 3 的 67% 和 PF 3 -TPA 的 86%）。在核中引入三苯胺单元促进了空穴注入能力，同时没有明显削弱低聚物的电子注入能力。制造多层器件 ITO/PEDOT-PSS/PF 3 -TPA 3 和 PF 3 -TPA/TPBI/LiF/Al 以研究两种低聚物的电致发光 (EL) 特性。两种低聚物都显示出

These terfluorenes exhibit intense blue fluorescence with excellent quantum yields both in solution ( approximately 100%) and in solid state (66-90%), and possess interesting reversible redox properties. Highly efficient blue light-emitting OLED devices were fabricated using 4aa and 4cc as emitters as well as

  通过 2-溴芴 (1) 和 2,7-氟代硼酸酯衍生物 (3) 的 Suzuki 偶联反应合成了新的三 (9,9-二芳基芴)，具有高分离产率 (63-86%)。ter(9,9'-spirobifluorene) (4aa) 的 X 射线结构分析表明共轭发色团采用螺旋构象。这种构象有效地释放芴部分之间的空间相互作用并防止发色团间相互作用。在芴的 C9 位置引入芳基非常有利于这些低聚物的热稳定性和形态稳定性。这些三芴在溶液（大约 100%）和固态（66-90%）中都表现出强烈的蓝色荧光，具有出色的量子产率，并且具有有趣的可逆氧化还原特性。使用 4aa 和 4cc 作为发射器以及空穴传输器制造了高效的蓝光 OLED 器件。该器件具有低开启电压（约 3 V）和高 EL 外量子效率（2.5-3%）。

  A class of complicated 9,9-diarylfluorenes as nonplanar building blocks were synthesized and utilized to prepare a novel H-shaped oligofluorene. High glass transition temperatures and excellent solubility of the obtained oligomers indicated the 9,9-diarylfluorenes would be promising building blocks for the construction of H-shaped optoelectronic materials.

  [GRAPHICS]9,9-Diaryl-2,7-dibromofluorene was synthesized by a triflic acid promoted Friedel-Crafts reaction. Introduction of diarylamino groups at its C2 and C7 positions by a Pd-catalyzed amination results in the formation of a novel class of triaryldiamines. The 9,9 diaryl substituents at the central linkage play a less important role in the photophyscial properties but affect the oxidation potential and improve the morphological stability of these new triarylamines.
