Description
技术领域
与相关申请的相互引用
本申请主张基于2019年9月5日的韩国专利申请第10-2019-0110309号的优先权，包含该韩国专利申请的文献中公开的全部内容作为本说明书的一部分。
本发明涉及新型化合物及包含其的有机发光器件。
背景技术
通常情况下，有机发光现象是指利用有机物质将电能转换为光能的现象。利用有机发光现象的有机发光器件具有宽视角、优异的对比度、快速响应时间，亮度、驱动电压和响应速度特性优异，因此正在进行大量的研究。
有机发光器件通常具有包括阳极和阴极以及位于上述阳极与阴极之间的有机物层的结构。为了提高有机发光器件的效率和稳定性，上述有机物层大多情况下由分别利用不同的物质构成的多层结构形成，例如，可以由空穴注入层、空穴传输层、发光层、电子传输层、电子注入层等形成。对于这样的有机发光器件的结构而言，如果在两电极之间施加电压，则空穴从阳极注入有机物层，电子从阴极注入有机物层，当所注入的空穴和电子相遇时会形成激子(exciton)，该激子重新跃迁至基态时就会发出光。
对用于如上所述的有机发光器件的有机物，持续要求开发新的材料。
