| titleOfInvention | Synthesis method of OLED intermediate and semiconductor material 1-hydroxypyrene |
| abstract | The invention discloses a synthesis method of an OLED intermediate and a semiconductor material 1-hydroxypyrene, which comprises the following steps: adding pyrene and a solvent I into a reaction vessel, uniformly stirring, adding a nitrosation reagent, stirring at 20-25 ℃, adding water into the obtained product, separating out a solid, and drying the separated solid to obtain 1-nitrosopyrene; mixing 1-nitrosopyrene and an alcohol solvent to form a suspension, introducing air or oxygen into the suspension, carrying out a light reaction until the 1-nitrosopyrene is reacted, adding BHT (butylated hydroxytoluene), concentrating at 45-50 ℃ to dryness, adding a solvent for recrystallization, and heating until the solution is clear; and then cooling to 20-25 ℃, filtering, and drying a filter cake to obtain the 1-hydroxypyrene. By adopting the method, the 1-hydroxypyrene with the purity of more than or equal to 99.1 percent can be obtained. |
