【摘要】 利用H eck偶联反应首次制备了两种主链含方酸基团的PPV型共聚物,其结构均经1H-NM R,FT-IR,元素分析确证。聚合物在常用有机溶剂中有良好的溶解性。DSC和TGA测试表明聚合物具有较好的热稳定性。首次将这两种聚合物应用于聚合物太阳电池,在1.5 AM照度下,开路电压0.50 V~0.55V,短路电流0.15 mA/cm2~0.11 mA/cm2。填充因子0.269~0.267,能量转换效率0.145%~0.098%。更多还原

【Abstract】 A novel series squaraine PPV were synthesized through a Heck coupling reactions,The polymers were characterized by（）¹H-NMR,FT-IR and elemental analysis.All these polymers are soluble in common solvent,such as THF,CHCl₃ and toluene.DSC and TGA show they have good thermal stability.Preliminary photovoltaics results show that these polymers are novel promising candidates for polymer solar cells and get a promising results.更多还原
