  Supramolecular green phosphorescent polymer iridium complexes for solution-processed nondoped organic light-emitting diodes

  摘要：

  In order to develop a novel class of solution-processable electroluminescent (EL) emitters, a bis(dibenzylammonium)-tethered host was synthesized and two green emission supramolecualr phosphorescent polymers (SPPs) were formed by utilizing the efficient non-bonding self-assembly between bis(dibenzo-24-crown-8)-functionalized iridium complex and bis(dibenzylammonium)-tethered monomers. The photophysical, thermal and electroluminescent properties of the SPPs were discussed in detail. These SPPs exhibit good thermal properties with high glass-transition temperature (T-g). The photophysical and electroluminescent properties are strongly dependent on the host unit structure of supramolecular polymers. The present work may provide a useful way to afford a new class of high-performance electroluminescent emitters for green emission PLEDs. (C) 2015 Elsevier B.V. All rights reserved.

  咔唑/低聚芴封端的己烷：溶液可加工的磷光有机发光二极管主体材料†

  摘要：

  烷基取代基有望改善用于有机光电器件溶液加工的芳香族化合物的溶解度和薄膜形态。然而，电子惰性烷基的引入通常会阻碍空穴和电子的注入以及在芳族单元之间/之间的转移，从而导致材料的电子性能降低，从而降低器件性能。在这里，我们提出了一种替代方法，即通过芳族双末端封端的烷基化反应，其中芳族咔唑和低聚芴在己基链的两端相连，以获得一系列咔唑/低聚芴封端的己烷。这些新设计的化合物显示出高溶解度，良好的薄膜形态，高的热稳定性，蓝色发射，高的三重态能量以及合适的前沿轨道能级，并具有良好的电荷传输性能；当用作溶液处理的磷光有机发光二极管（PhOLED）的主体材料时，这些分子表现出很高的器件性能，最大电流效率为28.0 cd A -1外部量子效率高达7.8％。我们结合烷基和芳族单元优点的策略为设计高性能可溶液加工的有机光电材料提供了一种有效的方法。

Combining the rigidity of the conjugated emissive cores and the flexibility of the peripheral alkyl‐linked carbazole groups, two series of highly efficient bipolar RGB (red, green, blue) emitters have been synthesized and characterized. The emissive cores are composed of

  This application discloses a white-light hyperbranched conjugated polymer, a method for preparing the same and its use. The polymer uses a red phosphorescent Ir(III) complex as a core and polyfluorene derivative blue fluorescent materials as a framework which either contains or does not contain carbazole derivatives, and the white light hyperbranched polymers realize white-light emission by adjusting the content of the red phosphorescent Ir(III) complex connected using the complementation of blue and red color. The electroluminescent spectrum of the conjugated polymer in the present application covers the whole visible light emission area and is close to the pure white light emission, by which the conjugated polymer could be used as a material used in light-emitting layer to prepare the organic electroluminescent devices.
