The invention provides an organic electroluminescent material and an organic light emitting device, belonging to the technical field of organic photoelectric materials. The general structural formula of the material is shown in Formula A. The core part of the material is a structure such as binaphthyl, bianthracene, triphenanthrene, pyrene, etc. It has a dark blue emission spectrum, and the conjugation range in the molecule is expanded through the double bond. In addition to the energy band width, the emission ranges from dark blue to sky blue. Experimental results show that the organic light-emitting device prepared by using the organic electroluminescence material of the present invention has the highest luminous efficiency of 5.9 cd/A, and the service life is obviously prolonged, which is an excellent OLED material. |
