A polymer light emitting material, wherein the material has a light emitting mechanism based on transition from an excited triplet state to a ground state or transition through an excited triplet state to a ground state of an electron energy level, and the material comprises a nonionic light emitting part which constitutes a part of the polymer or is bound to the polymer. The polymer light emitting material exhibits high light emission efficiency above 5%, which is the limit of external quantum efficiency of fluorescence and can be designed so as to have a large area and hence are suitable for mass production of organic light emitting devices.
一种聚合物
发光材料,其中该材料具有基于从激发的三重态到基态的跃迁或通过激发的三重态到电子能级的基态的跃迁的发光机制,并且该材料包括一种非离子发光部分,该部分构成聚合物的一部分或与聚合物结合。该聚合物
发光材料表现出高达5%以上的高发光效率,这是荧光外部量子效率的极限,并且可以设计成具有大面积,因此适合于有机发光器件的大规模生产。
