| titleOfInvention | Oligopoly thiophene derivative and preparation method thereof |
| abstract | The present invention relates to a kind of Oligopoly thiophene derivative and preparation method thereof, the preparation method of Oligopoly thiophene derivative mainly comprises: be dissolved in by 3TB in methylene dichloride, adds NBS stirring reaction, obtains 3TB-3Br; In there-necked flask, add EDOT and tetrahydrofuran (THF), temperature of reaction is controlled at-78 DEG C.Drip n-Butyl Lithium, after dripping, rise to room temperature gradually, and continue reaction.And then temperature of reaction is dropped to-78 DEG C, drip tributyltin chloride, after dripping, temperature of reaction is risen to room temperature gradually, be obtained by reacting EDOT tin reagent; Under nitrogen protection, in there-necked flask, add toluene, then add 3TB-3Br and EDOT tin reagent and palladium catalyst, back flow reaction obtains the crude product of 3TB-3EDOT, is isolated to pure 3TB-3EDOT.Its positively charged ion formed when electrochemical doping (or negatively charged ion) free radical is stable, can as novel organic electrochromic material. |
