Abstract
The invention discloses a fluoranthyl-containing arylamine compound and an organic electroluminescent device containing the fluoranthyl-containing arylamine compound, the general formula structure of the fluoranthyl-containing arylamine compound is as shown in the specification, L1 is absent, phenylene or naphthylene, L2 is phenylene or naphthylene, and further, when L2 is naphthylene, Ar1 and Ar2 are respectively and independently selected from phenyl, biphenyl, pyridyl, naphthyl or quinolyl; and when L2 is phenylene, Ar1 is selected from phenyl, biphenyl, pyridyl, naphthyl or quinolyl, and Ar2 is naphthyl or quinolyl. On the basis that fluoranthene has high rigidity and planarity and the aromatic amine compound characteristic of a conventional covering layer material, the fluoranthene-containing aromatic amine compound obtained through molecular design serves as the covering layer of an OLED, and the comprehensive effect is good.
Description
technical field [0001] The invention belongs to the field of organic electroluminescent materials, in particular to arylamine compounds containing fluoranthene groups and organic electroluminescent devices containing the same. Background technique [0002] With the development of electronic display technology, organic light-emitting devices (OLEDs) are widely used in various display devices, and the research and application of OLED light-emitting materials are also increasing. Among them, OLED capping layer materials require high refraction rate, low absorption coefficient, excellent molecular stability and crystallization resistance. The fluoranthene group has strong rigidity and good planarity, and can be used as a covering layer. In addition, arylamine compounds have been widely used as the covering layer of OLEDs, but arylamine compounds based on fluoranthene are used in organic electroluminescent materials There is little research in this field. Based on the above, st...
