Abstract

The invention belongs to the field of photoelectric materials and particularly relates to an organic blue light electroluminescent material with the structural formula as shown in the figure p, wherein r is a hydrogen atom, c1-c20 alkyl or c1-c20 alkoxy. The organic blue light electroluminescent material has relatively high lumo energy level and relatively low homo energy level so as to be beneficial to blue shift of light emitting wavelength of the organic blue light electroluminescent material; and the organic blue light electroluminescent material also has relatively high phosphorescent quantum efficiency as well as relatively good dissolving property and processability. The invention also provides a preparation method of the organic blue light electroluminescent material and application of the organic blue light electroluminescent material to an organic electroluminescent device.

Description

technical field

[0001] The invention relates to the field of optoelectronic materials, in particular to a blue-light organic electroluminescent material and its preparation method and application. Background technique

[0002] Organic electroluminescence refers to a luminescence phenomenon in which organic materials directly convert electrical energy into light energy under the action of an electric field. Due to the limitation of spin statistics theory, the theoretical internal quantum efficiency limit of fluorescent materials is only 25%. How to make full use of the remaining 75% of phosphorescence to achieve higher luminous efficiency has become a hot research direction in this field since then. The complexes of iridium, ruthenium, platinum, etc. can obtain high emission energy from their own triplet state, and the metal iridium (III) compound, due to its good stability, has mild reaction conditions during the synthesis process and has a high electron emission. The lumin...
