| titleOfInvention | Phosphinoxy group-modified dipyridophenazinyl red light/near-infrared thermally excited delayed fluorescence material, synthesis method and application thereof |
| abstract | A dipyridophenazine-based red light/near-infrared thermally excited delayed fluorescent material modified with a phosphinoxy group, a synthesis method and an application thereof, which relate to a thermally excited delayed fluorescent material, a synthetic method and an application thereof. The invention aims to solve the problems of the existing red/near-infrared TADF materials, such as the concentration quenching caused by the large polarity of molecules, and the problems of low efficiency and fast decay of electroluminescent devices. The structural formula is as follows: Synthetic method: 1. Prepare the intermediate; 2. Mix the intermediate, palladium acetate, sodium acetate, diphenylphosphine and N,N dimethylformamide, react at 150°C for 48 hours, oxidize, extract with water and dichloromethane, Combine the organic layers, remove the organic solvent after drying, and purify to obtain the dipyridophenazinyl red light/near-infrared thermal excitation delayed fluorescent material modified by the phosphine group. The material of the invention significantly improves the efficiency of the electroluminescent device, reduces the quenching effect, and enhances the stability of the efficiency of the electroluminescent device. The invention belongs to the field of preparation of fluorescent materials. |
