Abstract
Provided are a compound, an organic light-emitting element including the same, a display panel and a display device. The compound has a structure represented by Formula I. The organic light-emitting element includes an anode, a cathode and an organic thin film layer disposed between the anode and the cathode; where the organic thin film layer includes a light-emitting layer, and further includes any one or a combination of at least two of a hole transport layer, an electron blocking layer and an auxiliary light-emitting layer, and at least one of the hole transport layer, the electron blocking layer and the auxiliary light-emitting layer contains at least one of the compounds. The compound has a relatively shallow HOMO energy level, a relatively shallow LUMO energy level, a relatively high triplet energy level, an appropriate hole mobility, a relatively high Tg, a large molecular torque and good thermal stability.
