The present disclosure relates to the field of blue phosphorescent tetradentate cyclic-metal palladium complex luminescent materials, and discloses a blue phosphorescent tetradentate cyclic-metal palladium complex based on 4-aryl-3,5-disubstituted pyrazol, preparation and use thereof. The complex may be a delayed fluorescent and/or phosphorescent emitter. The complex has characteristics of high thermal decomposition temperature, high luminous intensity, and deep blue light emission and a narrow emission spectrum, therefore there are a huge application prospects in the field of blue light, especially in deep blue phosphorescent materials. |
