合成了具有相同骨架结构的两种新型聚合物PBDT-DEAITN和PBDT-DOAITN，并制备了它们的有机光伏器件。虽然这两种聚合物具有较低的光学带隙，PBDT-DEAITN和PBDT-DOAITN的光学带隙分别为1.52和1.58 eV，但它们的OPV电池在AM1.5G模拟太阳光下的功率转换效率相当有限，仅为1.25%和1.20%。通过结构模型计算，分析了OPV性能较低的原因。在此基础上，结合文献中对具有代表性的藜麦类聚合物的筛选结果，提出了基于ITN单元的高性能平面聚合物的设计策略。
Two novel copolymers PBDT-DEAITN and PBDT-DOAITN containing the same backbone of isothianaphthene (ITN) quinoidal and benzodithiophene (BDT) donor units are synthesized and their organic photovoltaic (OPV) devices are fabricated. Although these two polymers have rather low optical bandgaps, 1.52 and 1.58 eV for PBDT-DEAITN and PBDT-DOAITN, respectively, their OPV cells exhibit rather limited power conversion effi ciencies of 1.25% and 1.20% under an AM1.5G simulated solar light. The reasons for the low OPV performance are investigated by structure modeling calculation. Based on this and the screening results for the representative quinoidal polymers in the literatures, a strategy of designing highperformance planar polymers based on ITN unit is proposed.
