摘要: Embodiments of the present application disclose a boron-containing organic compound and applications thereof. The boron-containing organic compound is shown in the general formula (I):
The hole-transporting group of the pentyl group is beneficial to improve the hole-transporting performance of the compound on the one hand, and on the other hand, it can enhance the resonance performance of the molecule, so that when the boron-containing organic compound is applied to an organic light-emitting device, it can effectively improve its light extraction efficiency. Meanwhile, the cyclopentyl group can effectively increase the distance between molecules, and can inhibit the exciton quenching caused by the accumulation between molecules. When this boron-containing organic compound is applied to blue light materials, it can effectively improve the stability and life of the device.-
