Benzoxazole pyridine-based copper iodide complex orange luminous material

The invention discloses benzoxazole pyridine-based orange phosphorescent CuIN2P-type copper complex luminous material and a preparation method thereof. The phosphorescent complex of the invention is obtained by coordination reaction of copper iodide and a ligand and has a molecular structural formula: CuI(2-PBO)(o-Tol3P), wherein 2-PBO and o-Tol3P are respectively electrically-neutral ligands 2-(2-benzoxazole)pyridine and tris(o-methylphenyl)phosphine. The complex has small-molecular purification easiness and high luminous efficiency and is also easy to dissolve with an organic solvent. This material is obtained by directly mixing and reacting copper iodide and a ligand solution and has the advantages such as process simplicity, equipment simplicity, easy access of materials and low cost. This material may be used as a photoluminescent orange luminous material and may also be used a luminous layer phosphorescent material in an electroluminescent device composed of multilayer organic material. 本发明公开了种基于苯并噁唑基吡啶
