Paragraph 0096; 0097; 0098, (2018/08/28)
The invention discloses a doping material and its organic electroluminescent light emitting device, relates to organic photoelectric material technical field. The advantage of this invention is, of structural formula I of the present invention shown in nature with good electron acceptor dopant and the structural formula II shown with good electron donor nature of the doping material matrix materials is completed at a relatively low doping concentration has a higher hole mobility, high conductivity, and has better thermal stability and solubility, beneficial material into a film. The invention of the organic electroluminescent device includes a cathode, anode and one or a plurality of the organic material layer, the organic material layer is located between the anode and the cathode, the organic material layer in the at least one layer contains a dopant material of the present invention, the invention of the organic electroluminescent device has a lower driving voltage, high luminous efficiency and the luminous brightness, and has a long service life.
