| titleOfInvention | High-efficiency organic light-emitting materials and preparation and application thereof |
| abstract | The invention relates to tetrabenzotriphenyl olefin organic light-emitting materials which can be used in an organic electroluminescent device structure; the series of derivatives take tetrabenzotriphenyl compounds as a basis; through introduction of olefins on tetrabenzotriphenyl, aromatic amine, a substituted or unsubstituted polycyclic aromatic group, a substituted or unsubstituted aromatic heterocyclic group and other substituents continue to be introduced, the electronic transition can be regulated, and the demand of the light-emitting materials is met; the materials have quite high light-emitting efficiency, the light-emitting efficiency in a dilute solution is about 96%, and the light-emitting efficiency in a thin film can reach about 63%, so that the tetrabenzotriphenyl olefin compounds are indicated to have high light-emitting efficiency. Compared with tetrabenzotriphenyl, a preparation method of the tetrabenzotriphenyl olefin organic light-emitting materials is relatively simple in synthesis and purification and low in cost, and can meet the demand of industrialization development. The yield of the products is greatly improved, the purity is high, and the HPLC purity is more than 98%. Moreover, the prepared materials can achieve significant increase of the efficiency, and have both the film forming property and the life improved significantly. |
