| titleOfInvention | Organic small-molecule efficient room-temperature phosphorescent material based on aromatic imide and preparation and application thereof |
| abstract | The invention discloses an organic micromolecule high-efficiency room temperature phosphorescent material based on aromatic imide and a preparation method and application thereof. The structural formula of the high-efficiency room-temperature phosphorescent material is shown as a formula I, wherein in the formula I, R represents 1 or more substituent groups connected to a benzene ring and is selected from at least one of H, aliphatic hydrocarbon, aromatic hydrocarbon, heteroaromatic hydrocarbon and halogen; r 1 、R 2 、R 3 、R 4 And R 5 Independently selected from electron rich aromatic amine substituents containing at least one nitrogen, H or halogen, but not both. The phthalimide derivative provided by the invention has the characteristics of room-temperature phosphorescence property, high fluorescence quantum yield, easiness in derivatization, good stability and the like; the synthesis method is simple, the raw materials are cheap, the product yield is high, and the large-scale preparation can be realized; the carbazole-substituted phthalimide derivative has the advantages of high luminous efficiency, ultra-long afterglow, scribblability and the like. |
