通过Stille交叉偶联反应合成了三种基于噻吩并[3,4-c]吡咯-4,6-二酮和异靛蓝单元的随机共轭聚合物RP-TiI、RP-2TiI和RP-TVTiI。研究人员对新型聚合物的光学和电化学性能进行了研究。所得聚合物显示出广泛的吸收光谱和适合聚合物太阳能电池应用的能量水平。基于聚合物 RP-TiI 和 PC61BM 共混物的本体异质结器件的功率转换效率为 1.75%。
Three random conjugated polymers, RP-TiI, RP-2TiI and RP-TVTiI based on both thieno[3,4-c]pyrrole-4,6-dione and isoindigo units have been synthesized by Stille cross-coupling reaction. The optical and electrochemical properties of new polymers have been investigated. The resulted polymers showed broad absorption spectra and appropriate energy levels for polymer solar cell applications. The bulk heterojunction devices based on the blend of the polymer RP-TiI and PC61BM showed a power conversion efficiency of 1.75%.
