Description

technical field

[0001] The invention belongs to the technical field of electroluminescent materials, and in particular relates to an organic luminescent material containing a nitrogen heterocycle and an application thereof. Background technique

[0002] The use of organic materials to prepare various functional devices, especially for photoelectrically responsive functional devices, such as common organic electroluminescent devices, organic solar cell devices, organic field effect transistor devices and organic photosensitive sensor devices, has attracted more and more attention. .

[0003] Organic electroluminescent device is a device technology that realizes electroluminescence by introducing one or more layers of organic films on the cathode and anode. It can achieve ultra-thin, flexible and transparent performance, and is used in flat panel display and lighting industries. increase year by year.

[0004] In order to achieve high-efficiency and long-life luminescence, t...
