| titleOfInvention | Containing the polymkeric substance and preparation method thereof of indoles [3,2-b] carbazole unit |
| abstract | The present invention is containing indoles [3,2-b] polymkeric substance of carbazole unit, there is the structural formula shown in following general formula I, its preparation method includes following steps: get two bromo indoles [3,2-b] boric acid ester of carbazole and arylidene, add in flask, and add consisting of phase-transferring agent tri-n-octyl methyl ammonium chloride and catalyzer, pass into argon gas, then add solvent toluene and hydrolytic reagent Nan 2 cOn 3 the aqueous solution, temperature rising reflux reacts; Add the boric acid ester of arylidene, backflow, polyreaction is complete, obtains mixing solutions; Adopt methyl alcohol to carry out preliminary sedimentation to mixing solutions, after throw out filtration drying, cross post and purify, gained material again precipitates after drying through methyl alcohol and get final product.The present invention well can be dissolved in toluene, tetrahydrofuran (THF), methylene dichloride, chloroform etc. and common are in machine solvent, is convenient to film forming, has good processing characteristics, can send stronger fluorescence, become the OLED material that a class gets a good chance of; Operation is simple and feasible for this polymerization process, and productive rate is higher. |
