Abstract
Provided are a compound and an organic electro-optical device containing the same. The compound has a structure represented by Formula I. The organic electro-optical device comprises an anode, a cathode, and at least one organic thin film layer located between the cathode and the anode. The molecule of the compound provided by the present disclosure has higher rigidity, a large conjugated system, a deeper LUMO energy level, a higher triplet energy level and good molecular stability, and is not easy to crystallize, and thus the compound can be used as an electron transport material or a hole blocking material of the organic electro-optical device, facilitating the reduction of the turn-on voltage of the device, the improvement of current efficiency and the increase of service life.
