The present invention is in the field of organic electroluminescence, and specifically relates to a fused ring carbazole tetradentate metal platinum (II) complex and use thereof. In the present invention, a tetradentate metal platinum (II) complex phosphorescent material is obtained by introducing a five-membered heterocyclic system such as benzofuran or benzothiophene at the 5, 6-positions of carbazole. Increasing the ratio of the local state (LE) in the excited triplet state of the cyclic tetradentate platinum (II) complex leads to a lower shoulder peak, which improves the luminescence color purity of the materials, which in turn increases device lifetime. The materials provided by the present invention all have good chemical stability and thermal stability and are easy to fabricate an evaporation-type OLED device.
