Abstract: The present invention relates to the technical field of organic light-emitting materials, and provides a tetradentate cyclometalated platinum (II) complex based on an oxygen atom linkage and containing phenyl acridine and an application thereof. The tetradentate cyclometalated platinum (II) complex has the structure as represented by general formula (I). (I) The cyclometalated platinum (II) complex in the present invention adopts a tetradentate ligand, is high in rigidity, and can improve the light stability of a light-emitting material. At the same time, the complex molecule can strongly emit light, and therefore can be used as a light-emitting material in an OLED device.
