Paragraph 0041; 0044-0046; 0064; 0070; 0076; 0085; 0094, (2021/02/10)
The invention discloses a novel bipolar green phosphorescent host material and an OLED light-emitting device containing the same. The structural general formula of the novel bipolar green phosphorescent host material is shown in the specification. The novel bipolar green phosphorescent host material can greatly reduce the driving voltage of the device, greatly reduce the consumption of electric energy and significantly improve the luminous efficiency. In addition, by reducing the driving voltage, the service life of the organic light-emitting device is remarkably prolonged.
