摘要
利用Stille偶联聚合反应,将二溴苯并噻二唑、2,5-二噻吩双三丁基锡、9,9-二辛基2,7-二溴芴进行聚合,得到了一种在可见光区具有宽发射范围的三元共聚物,该聚合物的发射光谱涵盖了整个可见光区,发光峰位于470.7,498.9,654.2nm,具有成为单层聚合物白光材料的潜力。
A conjugated polyfluorene copolymer with broad emission in the visible region was synthesized by Stille coupling reaction through the polymerization between 2,5-bis（tributylstannyl）thiophene,4,7-dibromo-2,1,3-benzothiadiazole and 2,7-dibromo-9,9-dioctylfluorene.The obtained copolymer possessed of broad emission spectrum in visible region with the peak of 470.7,498.9,654.2 nm,indicating the potential application in polymer white emission materials.
