Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and in particular relates to an organic semiconductor material and a preparation method thereof. Background technique [0002] With the development of the information age, organic electroluminescent flat panel displays (OLEDs) with high efficiency, energy saving and light weight and large-area white light illumination have attracted more and more attention. Electroluminescent devices, etc. need to achieve full-color light emission, and blue is essential among the three primary colors. Improving the luminescence performance of blue light is of great significance for the realization of organic electroluminescent full-color display and solid-state luminescent lighting. At present, the luminous efficiency, stability and carrier transport performance of blue light-emitting materials are not good, which affects the luminous efficiency of the entire device. Contents of the invention [0003]...
