The invention discloses a benzoxazolyl based CuN2P2 orange phosphorescent material and a preparation method. The phosphorescent complex of the benzoxazolyl based CuN2P2 orange phosphorescent material is obtained through cuprous salt and ligand complexation, a molecular structure of the phosphorescent complex is [Cu(2-QBO)(Xantphos)]PF6, the 2-QBO and the Xantphos in the formula are respectively electrically neutral bidentate chelating ligand 2-(2-benzoxazole) quinoline and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene. The complex has the advantages that micro-molecules are easy to purify and luminous efficiency is high and has high heat stability. The benzoxazolyl based CuN2P2 orange phosphorescent material is obtained through direct mixing and reaction of Cu(CH3CN)4PF6 and a dichloromethane solution of the complex, has the advantages that a process is simple and convenient, a device is simple, raw materials are easy to obtain, cost is low and the like, can serve as an orange photo-luminescent material and can also serve as a luminous-layer phosphorescent material consisting of multiple layers of organic materials and used in an electroluminescent device.
