| titleOfInvention | Tetrastyryl blue light material containing benzimidazole unit and preparation method and application |
| abstract | The invention discloses a tetrastyryl blue light material containing benzimidazole units, as shown in structural formula I or II, wherein: R 1 is H, tert-butyl, n-butyl, and hydroxyl. R 2 is an alkyl group. First prepare 2-nitro-N-tert-butylphenylaniline or 2-nitro-N-n-butylaniline precursor and 4-aldehyde tetraphenylene precursor, and then obtain formula I or II through cyclization reaction compound. The preparation method of the compound is easy to operate, the reaction is mild and the yield is high, the compound has high decomposition temperature and glass transition temperature, and exhibits blue fluorescence and good monochromatic performance, and the OLED device prepared by using the compound as a light-emitting material has blue light. Emission, start-up voltage 3.3V, maximum brightness efficiency 1.48cd/A. |
