  用于高效电致磷光器件的Spiro配置双极主体材料

  摘要：

  在这项研究中，我们合成并表征了一系列基于螺双芴的双极化合物（D2 ACN，DNPACN，DNTACN和DCzACN），其中双氰基取代的联苯分支与带有各种二芳基胺的供体联苯分支正交连接，充当受体单元，可以对形态稳定性，三重态能量，双极传输行为以及HOMO和LUMO能级进行微调。这些新化合物具有令人鼓舞的物理性能，以及以平衡的迁移率传输电子和空穴的能力，使其适合用作具有绿色铱基或红色铱的高效磷光有机发光二极管（PhOLED）的主体材料。基磷光体作为发光层（EML）。我们采用了多层结构，以有效地将空穴和电子限制在EML内，从而防止了激子扩散并提高了器件效率。包含掺有红色发射极[Os（bpftz）的D2 ACN的设备2（PPhMe 2）2 ]（bpftz = 3-（三氟甲基）-5（4-叔丁基吡啶基）1,2,4-三偶氮酸酯）给出了饱和红色电致磷光，其CIE坐标为（0.65，0.35），且显着在1000

  The present invention relates to an organic mixture and an application thereof in organic electronic devices. The organic mixture comprises a spirofluorene organic compound containing a fused heterocyclic ring and an aromatic fused heterocyclic organic compound containing an electron-donating group. A combination of the two materials may be used as a host material of a phosphorescent organic light-emitting diode (OLED), which may use the energy of excitons and balance the charge transport to the greatest extent and which may effectively reduce the concentration of excitons and the operating voltage of a corresponding device, thereby effectively improving the efficiency and service life of the related electronic device in order to provide an effective solution for improving the overall performance of an organic electronic device.
