Problems solved by technology

[0002] In the prior art, organic light emitting diodes (Organic Light Emitting Diodes) have self-luminous properties, and the materials that dominate their luminescence are mainly electroluminescent materials. However, the low luminous efficiency of current electroluminescent materials often leads to organic light emitting diodes Therefore, it is necessary to provide an electroluminescent material with high luminous efficiency, a preparation method of the electroluminescent material and a light-emitting device

Abstract

The application provides an electroluminescent material, a preparation method of the electroluminescent material and a luminescent device. Tert-butylpyrene with triplet-state-triplet-state fusion and a carrier transporting unit are simultaneously connected to the same carbon of cyclohexane with a large steric hindrance structure to form a tetrahedral structure, thereby effectively reducing the concentration quenching effect of a pyrene structure, and increasing the film fluorescence quantum efficiency; meanwhile, the transporting unit with high carrier mobility is introduced, so that the balance of carrier transporting is improved, and the recombination probability is increased, thereby achieving the electroluminescent material with high electroluminescent efficiency capable of emitting blue light, the preparation method of the electroluminescent material and the luminescent device.

Description

technical field [0001] The present application relates to the display field, in particular to an electroluminescence material, a preparation method of the electroluminescence material and a light emitting device. Background technique [0002] In the prior art, organic light emitting diodes (Organic Light Emitting Diodes) have self-luminous properties, and the materials that dominate their luminescence are mainly electroluminescent materials. However, the low luminous efficiency of current electroluminescent materials often leads to organic light emitting diodes Therefore, it is necessary to provide an electroluminescent material with high luminous efficiency, a preparation method of the electroluminescent material, and a light-emitting device. Contents of the invention [0003] The present application provides an electroluminescence material with high electroluminescence efficiency, a preparation method of the electroluminescence material and a light emitting device.
