One kind of novel form benzoxazole and quinoxaline cuprous complex luminescent material groups

Luminescent material and its preparation method The present invention discloses a novel crystalline form of a yellow phosphor copper complexes. Phosphorescent complexes of the present invention, a monovalent copper salt derived from the ligand complex, the molecular structure of [Cu (QBO) (PPh3) 2] PF6, and wherein PPh3 QBO electrically neutral ligand triphenylphosphine and 2- (2-benzoxazolyl) quinoline. The complex includes both small molecules and easy purification and high emission efficiency advantages, but also has high thermal stability. The material is Cu (CH3CN) 4PF6 obtained via a solvothermal reaction with ligand in a mixed solvent of ethanol and water by having a simple process, simple equipment, raw material is easily available and low cost. The material can be used as electrically yellow photoluminescent material, organic material can be used as a multilayer phosphorescent material emitting layer of electroluminescent devices.
