Problems solved by technology
Due to the large difference in the transport speed of the carrier holes and electrons, the carrier imbalance of the device is caused, and the recombination area of electrons and holes tends to be biased towards one electrode, which leads to the quenching of excitons and loss of light, and the luminous efficiency is reduced. It will cause uneven light color and shorten the lifespan

Abstract
The invention provides an anthracene-containing compound, a synthesis method thereof, and an OLED therefrom, and relates to the technical field of organic photoelectric materials. In the invention, different ligands are connected to a main structure formed by connecting anthracene and acridine, thus regulating molecular weight, [pi]-conjugation degree and electrophilicity of the material, so thatthe compound is high in carrier transport capability, makes charge transmission easy, is increased in glass transition temperature, is not liable to crystallize and has good film forming performance.The synthesis method is simple and easy to carry out. The compound can be used for producing the OLED, especially as an electron transfer layer in the OLED. The OLED has high luminous efficiency and long service life.
Description
technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to an anthracene-containing compound, a synthesis method thereof, and an organic light-emitting device. Background technique [0002] Organic light-emitting device (OLED), as a new type of flat panel display, has self-illumination, wide viewing angle, full curing, full-color, fast response, high brightness, low driving voltage, thin thickness, light weight, and can be produced in large In recent years, OLED has been more and more used in the display market, and has become the most potential panel display technology at present. [0003] The structure of an organic light-emitting device generally includes a cathode, an anode, and an organic layer between the two. The organic layer mainly includes a light-emitting layer and each organic layer for balancing carrier injection and transport. The organic layer mainly includes: Injection materials, carrier transport...
