    • An organic light-emitting device comprises an anode, a cathode, a light-emitting layer between the anode and the cathode and a hole transporting layer between the anode and the light-emitting layer. The hole transporting layer comprises a hole-transporting material having a triplet energy level, and a triplet-quenching unit having a triplet energy level that is lower than the triplet energy level of the hole-transporting material. The triplet quenching unit is selected from the group consisting of polyaromatic hydrocarbons such as 2,6-anthracenes, 9,10-anthracenes and derivatives thereof; anthanthrenes and derivatives thereof; distyryl aryls and derivatives thereof such as distyrylbenzenes, distyrylbiphenyls, stilbenes, fulvenes, dibenzofulvenes, perylenes, linear polyenes (from 2 to 6 alkenes) and cyclic polyenes, each of which may optionally be substituted with one or more substituents.
    • 有机发光器件包括阳极,阴极,阳极和阴极之间的发光层以及阳极和发光层之间的空穴传输层。 空穴传输层包括具有三线态能级的空穴传输材料和具有低于空穴传输材料的三线态能级的三线态能级的三重态骤冷单元。 三重态猝灭单元选自聚芳烃如2,6-蒽,9,10-蒽及其衍生物; 茴香及其衍生物; 二苯乙烯基芳基及其衍生物,如二苯乙烯基苯,二苯乙烯基联苯,二苯乙烯,富二烯,二苯并呋喃,苝,线性多烯(2至6个烯烃)和环状多烯,它们各自可以任选被一个或多个取代基取代。
