A novel compound in which a delayed fluorescence component due to TTA accounts for a high proportion of emissive components is provided. The organic compound includes an anthracene skeleton, an arylene group, and a substituted or unsubstituted heterocyclic group including a carbazole skeleton. The anthracene skeleton and the substituted or unsubstituted heterocyclic group including the carbazole skeleton are bonded to each other through the arylene group. The anthracene skeleton includes an aryl group at the 2-position or the 3-position.
本研究提供了一种新型化合物,其中 TTA 导致的延迟荧光成分在发射成分中所占比例较高。该有机化合物包括蒽骨架、芳烯基和包括咔唑骨架在内的取代或未取代杂环基团。蒽骨架和包括咔唑骨架的取代或未取代杂环基团通过芳基相互键合。蒽骨架包括位于 2 位或 3 位的芳基。
