Description

technical field

[0001] The invention belongs to the technical field of photoelectric materials, and in particular relates to an organic semiconductor material, its preparation method and application. Background technique

[0002] In 1987, Tang and VanSlyke of Eastman Kodak Company in the United States reported a breakthrough in the research of organic electroluminescence. To achieve full-color display and lighting applications, blue light is essential among the three primary colors. Since blue light has the highest energy, as long as there are better materials, green light and red light can be obtained through various methods. Therefore, 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. However, due to the high energy, wide energy gap, luminous efficiency, stability and carrier transport performance of blue light, it is not very good. There...
