A porphyrin-diketopyrrolopyrrole-containing polymer (poly(porphyrin-diketopyrrolopyrrole) (PPDPP)) shows impressive molar absorption coefficients from λ=300 to 1000 nm. The photophysical and structural properties of PPDPP have been studied. With PPDPP as the electron donor and [6,6]-phenyl C butyric acid methyl ester (PC BM) as the electron acceptor, the bulk heterojunction polymer solar cell showed overall power conversion efficiencies of 4.18 and 6.44 % for as-cast and two-step annealing processed PPDPP:PC BM (1:2) active layers, respectively. These results are quite impressive for porphyrin-containing polymers, especially when directly included in the π-conjugated backbone, and offer interesting perspectives for the design of new materials based on this chromophore.
一种含卟啉-二酮吡咯并吡咯的聚合物（聚（卟啉-二酮吡咯并吡咯）（PPDPP））在λ = 300至1000 nm范围内显示出令人印象深刻的摩尔吸收系数。已对PPDPP的光物理和结构性质进行了研究。以PPDPP作为电子供体，[6,6]-苯基丁酸甲酯（PC BM）作为电子受体，对于浇铸态和两步退火处理的PPDPP:PC BM（1:2）活性层，本体异质结聚合物太阳能电池的总功率转换效率分别为4.18%和6.44%。对于含卟啉的聚合物而言，这些结果相当令人印象深刻，尤其是当卟啉直接包含在π共轭主链中时，并且为基于这种发色团的新材料设计提供了有趣的前景。
