| abstract |
The invention provides an organic luminescent material with excellent performance and a preparation method thereof, and proposes an organic compound, which introduces an acridine functional group with high electron hole transport efficiency and a helical structure with structural rigidity and high thermal stability. In terms of chemical structure design, it is combined with triarylamines with excellent hole transport properties and 9,9-dimethylfluorene with excellent electron transport materials to form a class of compounds with high thermal stability and excellent luminous efficiency. Different substituents The introduction of the material can change the electronic transition, so that the luminous peak position can be adjusted, and the device made of the material of the invention can meet the needs of industrial production. |
