Sub-injection, transmission performance, material electroluminescence performance, service life, color purity, matching between various materials and between electrodes, etc., there are still many problems that have not been solved. In particular, the luminous efficiency and service life of light-emitting elements have not yet met the practical requirements, which greatly limits the development of OLED technology.
有机电致发光主要分为荧光和磷光,但根据自旋量子统计理论,单重态激子和三重态激子的概率为1:3,即来自单重态激子辐射跃迁的荧光的理论极限为25%,三重态激子辐射跃迁的荧光的理论极限为75%。如何利用75%的三线态激子的能量成为当务之急。1997年Forrest等发现磷光电致发光现象突破了有机电致发光材料量子效率25%效率的限制,引起人们对金属配合物磷光材料的广泛关注。从此,人们对磷光材料进行大量的研究。Organic electroluminescence is mainly divided into fluorescence and phosphorescence, but according to the theory of spin quantum statistics, the probability of singlet excitons and triplet excitons is 1:3, which is the theoretical limit of fluorescence from singlet exciton radiative transitions is 25%, and the theoretical limit of the fluorescence of triplet exciton radiative transitions is 75%. How to utilize the energy of 75% triplet excitons becomes a top priority. In 1997, Forrest et al. found that the phenomenon of phosphorescent electroluminescence broke through the limit of 25% quantum efficiency of organic electroluminescent materials, which aroused extensive attention to metal complex phosphorescent materials. Since then, people have carried out a lot of research on phosphorescent materials.
鉴于以上原因,特提出本发明。In view of the above reasons, the present invention is proposed.
