一种三基色聚合物电致白光材料及其制备方法
摘要：
一种三基色聚合物电致白光材料，是具有下述结构通式的聚合物：式中：x＝0.0001～0.5；y＝0.0001～0.5。其制备方法是将2,7-双(4,4,5,5-四甲基-1,3,2-二氧杂硼烷-二基)-9,9-二辛基芴、2,7-二溴-9,9-二辛基芴、2,7-二溴-9-芴酮、4,7-二-2’-(5’-溴)-噻吩-2,1,3-苯并噻二唑按照100∶50～100∶0.02～50∶0.02～50的摩尔比混合，加入四(三苯基磷)合钯和甲基三辛基氯化铵、在甲苯及2mol/L碳酸钠溶液中，60～120℃氮气保护条件下回流搅拌反应得到。以本发明聚合物电致白光材料制成的结构为ITO/PEDOT/本发明白光材料/Ca/Al的器件电致发白光，电致发光光谱具有明显的红光、绿光和蓝光峰。
摘要（英）：

A three primary colours polymer white light emitting material is polymer with the structural general formula shown as below. In the formula, x is 0.0001-0.5 and y is 0.0001-0.5. The preparation method comprises the following steps: mixing 2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9,9-dioctylfluorene, 2,7-dibromo-9,9-dioctylfluorene, 2,7-dibromo-9-fluorenone and 4,7-bis-2'-(5'-bromo)-thiophene-2,1,3-benzothiadiazole according to a molar ratio of 100:50-100:0.02-50:0.02-50, adding trtrakis(triphenylphosphine)palladium and methyl trioctyl ammonium chloride, and refluxing and stirring to react in toluene and 2mol/L of sodium carbonate solution at 60-120 DEG C under the protection of nitrogen. The element prepared from the polymer white light emitting material with the structure of ITO/PEDOT/the white light emitting material/Ca/Al can emit white light through electrofluorescence and the electroluminescent light spectrum has obvious red light, green light and blue light peaks.
