Abstract

The invention discloses a compound taking cycloheptene as a core and an application of the compound on organic light-emitting devices. The compound has strong rigidity due to the cycloheptene structure, and after the compound is connected with a carbazole derivative long-chain branch structure, the compound has the characteristics of difficult crystallization and aggregation performance among molecules, good film-forming property and the like. According to the compound disclosed by the invention, the parent nucleus is bipolar, the branched chains are electron donating groups, and the electrondonating capacities of the branched chain groups are different, so that the material HOMO energy levels are different, and the compound can be used as materials of different functional layers; in addition, the compound provided by the invention has a relatively high triplet state energy level, can effectively block energy loss, and is beneficial to energy transfer. Therefore, after the compound disclosed by the invention is applied to OLED devices as an organic electroluminescent functional layer material, the current efficiency, the power efficiency and the external quantum efficiency of thedevices are greatly improved; and meanwhile, the service life of the devices is obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a compound with cycloheptene as the core and its application in organic electroluminescent devices. Background technique [0002] Organic electroluminescence (OLED: Organic Light Emission Diodes) device technology can not only be used to manufacture new display products, but also can be used to make new lighting products, and is expected to replace the existing liquid crystal display and fluorescent lighting, and has a very wide application prospect . The OLED light-emitting device is a sandwich structure, including electrode material film layers, and organic functional materials sandwiched between different electrode film layers. Various functional materials are superimposed on each other according to the application to form an OLED light-emitting device. As a current device, when a voltage is applied to the electrodes at both ends of the OLED light-emitting device, and ...
