Benzoxazolyl isoquinoline cuprous complex luminous material

Abstract

The invention discloses a crystal-form orange red cuprous complex phosphorescent material based on benzoxazolyl isoquinoline and a preparation method of the material.The phosphorescent complex is obtained through complexing of a cuprous salt and a ligand, and the molecular structural formula of the phosphorescent complex is [Cu(2-iQBO)(POP)]PF6, wherein 2-iQBO and POP in the formula are electrically neutral heterocyclic ligand benzoxazolyl isoquinoline and bis[(2-diphenylphosphino)phenyl] ether respectively.The complex not only has the advantages that small molecules are easy to purify and the luminous efficiency is high, but also has high thermal stability; the material is obtained through direct mixing and reacting of Cu(CH3CN)4PF6 and an acetonitrile solution of the ligand, and the advantages that the technology is simple and convenient, equipment is easy, the raw materials are easy to obtain, and the cost is low are achieved; the material can serve as an orange red photoluminescence phosphorescent material and can also serve as a luminous layer phosphorescent material in an electroluminescent device composed of multiple layers of organic materials.

Description

technical field [0001] The invention relates to the technical field of luminescent materials, to the fields of photoluminescent materials and electroluminescent materials, in particular to the field of organic electroluminescent materials. Background technique [0002] With the development of the times, mankind has entered the information age, and the current large-scale information technology revolution has played a huge role in the direction of social change. Nowadays, the amount of information is huge, information transmission is very fast, and information processing is fast. Although highly integrated electronic devices based on inorganic semiconductor materials and devices such as silicon and germanium are developing rapidly, their information transmission rate is still limited and "electronic bottlenecks" ". In order to break through this bottleneck, optoelectronic technology emerged as the times require, and display technology, one of the important fields of optoelec...
