Three non-fullerene acceptors (NFAs) with varying alkyl chain sizes and lengths but constant fluorine atoms were synthesized. BO-17F and HD-17F, with optimal fluorination, exhibit improved molecular packing and morphology, achieving efficiencies of 14.2% and 14.4%. This work highlights the importance of fine-tuning alkyl chains and fluorination levels in organic solar cells.
合成了三种具有不同烷基链尺寸和长度但氟原子数量恒定的非富勒烯受体（NFA）。具有最佳氟化程度的BO-17F和HD-17F表现出改善的分子堆积和形态，实现了14.2%和14.4%的效率。这项工作突出了在有机太阳能电池中微调烷基链和氟化水平的重要性。
