Abstract TB322; 近年来,有机稠环化合物在太阳能领域取得了突破性进展.本文采用非共价键构建稠环化合物的策略设计合成了两个以苯并二噻吩二酮为中心核,双氰基茚满二酮或二氟双氰基茚满二酮为端基的A-D-A'-D-A型共轭小分子BDD-IC和BDD-IC4F.通过紫外-可见吸收光谱、电化学循环伏安法及密度泛函理论(DFT)计算对其光物理和电化学性质进行了研究,同时以这两个小分子作为受体材料制备了全小分子有机太阳能电池器件,研究了其光伏特性.研究结果表明,有氟取代的小分子BDD-IC4F比BDD-IC具有更宽的光学吸收,更深的HO-MO和LUMO能级以及更高的热力学稳定性,基于BDD-IC4F的光伏器件获得了0.21％的光电转换效率.
