Provided are an organic electroluminescence device, which shows high luminous efficiency, is free of any pixel defect, and has a long lifetime, and a material for an organic electroluminescence device for realizing the device. The material for an organic electroluminescence device is a compound having a π-conjugated heteroacene skeleton crosslinked with a carbon atom, nitrogen atom, oxygen atom, or sulfur atom. The organic electroluminescence device has one or more organic thin film layers including a light emitting layer between a cathode and an anode, and at least one layer of the organic thin film layers contains the material for an organic electroluminescence device.
本文提供了一种发光效率高、无任何像素缺陷且使用寿命长的有机电致发光器件,以及一种用于实现该器件的有机电致发光器件材料。有机电致发光器件的材料是一种具有与碳原子、氮原子、氧原子或硫原子交联的π-共轭杂芳烯骨架的化合物。有机电致发光器件具有一层或多层有机薄膜层,包括阴极和阳极之间的发光层,有机薄膜层中至少有一层含有有机电致发光器件的材料。
