  Synthesis and properties of novel spirobifluorene-cored dendrimers

  摘要：

  Two novel spirobifluorene-cored dendrimers containing polyphenylene dendrons with the carbazole (spiro-Cz) and cyano surface groups (spiro-CN) were synthesized and characterized. Both the dendrimers show good solubility in common organic solvents. Spiro-Cz is amorphous even when it is obtained directly from organic solvents and an extremely high glass transition temperature of 332 degrees C is detected. These dendrimers can be reversibly oxidized and reduced in electrochemical measurements. They are blue fluorescent with small red-shift in solid film absorption and fluorescence spectra. These advantageous merits are suggested to benefit from the combined contribution from the spirobifluorene core and the bulky polyphenylene dendrons. They were used as emitting layer to fabricate organic light-emitting diodes (OLEDs). Deep-blue electroluminescence was obtained for both dendrimers devices. (C) 2011 Elsevier Ltd.

  具有咔唑表面基的per双酰亚胺双核树枝状大分子的合成和发光性质

  摘要：

  设计并合成了一组of双酰亚胺（PBI）核树枝状大分子。将在外围含有咔唑官能团的聚亚苯基树枝状分子连接到PBI核上，以期控制分子间的相互作用并调节树枝状聚合物的电荷传输能力。研究了它们的光物理，电化学和热性能。光谱数据表明，咔唑周边和PBI核之间共存有能量转移和光诱导的电荷转移，竞争影响了这些树枝状聚合物的发光性能。通过溶液法将这些树枝状聚合物作为非掺杂发光层来制造红色OLED。与那些模型化合物相比，带有咔唑的树枝状聚合物表现出改善的EL性能。

As a pleasant surprise, the troublesome aggregation-induced red shift of the emission of Ir-complex 2 could be totally suppressed by the bulky TIPSE moieties. Ir-complex 2 displays pure blue emission in a solution-processed, non-doped OLED (non-optimized) with moderate efficiency and without
