Compound with spirodimethylanthracene-fluorene and nitrogenous six-membered heterocycles and application thereof in organic light-emitting devices
The invention discloses a compound with spirodimethylanthracene-fluorene and nitrogenous heterocycles and application thereof in organic light-emitting devices. With spirodimethylanthracene-fluorene structure, the compound herein has great rigidity. After nitrogenous six-membered heterocyclic long-chain branch structure is linked to the compound, the compound features rarity of intermolecular crystallization and gathering, good film-forming capacity and the like. Since the stem nucleus is bipolar and the branch chains are electron-withdrawing groups which have different electron-withdrawing capacities, materials have different HOMO (highest occupied molecular orbital) energy levels and may act as different functional layer materials. In addition, with high trilinear energy level, the compound can effectively block energy loss and facilitate energy transfer. Therefore, after the compound is applied as an organic light-emitting functional layer material to OLED devices, all current efficiency, power efficiency and external quantum efficiency of the devices can be greatly improved. Furthermore, the service lives of the devices are significantly extended.
