A Class of Thermally Activated Delayed Fluorescent Materials and Organic Electroluminescent Devices Based on Arylboron Derivatives |
| abstract |
The invention relates to a thermally activated delayed fluorescent material and an organic electroluminescent device based on aryl boron derivatives, which have the structure shown in formula A. The invention also relates to an organic electroluminescence device, which comprises a luminescent layer, and the luminescent dye in the luminescent layer is the thermally activated delayed fluorescent material. The singlet-triplet energy gap of thermally activated delayed fluorescent materials is very small. At room temperature, triplet excitons can be converted to triplet excitons by thermal activation to emit light. The thermally activated delayed fluorescent material has simple synthesis, high luminous efficiency, small concentration quenching effect and good solubility. Organic electroluminescent devices based on such materials can achieve higher efficiency and better device stability. |
