Tetradentate ring metal platinum complex with 4 aryl pyrazole and preparation method and application

摘要

The present invention relates to the field of blue light phosphorescent tetradentate ring metal platinum complex luminescent material, discloses a blue light phosphorescent tetradentate ring metal platinum complex based on 4 aryl pyrazole, and its preparation method and application. The complex can be a delayed fluorescent and/or phosphorescent emitter with characteristics such as high thermal decomposition temperature, high quantum effect, being equipped with blue luminescence and narrow emission spectrum. Therefore, it has great application prospect in the field of blue light, especially dark blue phosphorescent material.
