摘要
通过stille偶联聚合合成了带烷基链连二噻吩与苯并二噻吩二酮类π-π共轭聚合物。利用核磁共振氢谱、元素分析和凝胶渗透色谱对聚合物进行了表征。聚合物光学性能和电化学性能分别通过紫外可见光谱和循环伏安曲线测定,结果显示,在可见光区有较好的吸收性能及给出电子的能力,并利用其为给体,通过旋涂法制备了聚合物太阳能电池器件,光电转化效率为0.028%。这类聚合物在有机溶剂中溶解性能好,在空气中稳定性高,是一种潜在的有机太阳能电池材料。
π-conjugated polymers containing bithiophene and benzodithiophene were synthesized by stiile coupling polymerization. The polymers were characterized by 1H-NMR, elemental analysis and gel permeation chromatography (GPC). The photovoltaic and electrochemical properties of the polymers were studied by UV-Vis spectrophotometry and electrochemistry tests, and the polymers showed relatively good absorption in visible region and electron donor ability. Organic photovoltage (OPV) devices fabricated by solution-processing have a power conversion efficiency (PCE) of 0. 028%. These polymers with a high solubility in organic solvent and good stability in the air are potential active materials for OPV devices.
