| 摘 要： | 苯并呋喃衍生物是一种具有高荧光效率、高热及光稳定性和优良空穴传输能力的蓝光发光材料。采用二(溴甲基)苯与溴代邻羟基苯甲醛发生Knoevenagel反应制备出了二溴代苯并呋喃衍生物,再通过与苯二硼酸发生Suzuki偶合,合成出了一种苯并呋喃基新型蓝光高分子材料(PBF)。利用荧光光谱仪(PL)、紫外光谱仪(UV)、差示扫描量热仪(DSC),研究了其相应的光学和热物理学性质。所得聚合物在膜状态下的PL分析表明,其最大荧光发射波长为444 nm,是一种典型的蓝光发光材料;DSC研究表明,聚合物在50~200℃温度范围内无明显的玻璃化转变和晶体熔融现象,表现出优良的热稳定性。该聚合物易溶于CHCl3、THF等有机溶剂,可旋涂成膜,易于加工,是一种具有应用价值的蓝光发光材料。

| Abstract: | Benzofuran derivates are hole transport materials with blue light-emitting property.They have high fluorescence quantum yield and thermal stability.The di-bromobenzofuran derivate was synthesized with bis(bromomethyl) benzene and 5-bromo-2-hydroxy-benzaldehyde through Knoevenagel reaction and then the polymer reacted with benzofuran(PBF) through Suzuki coupling reaction.The light emitting property was studied by using UV and PL spectroscopy while their thermal stability was studied by DSC.The PBF was found ... |
