The development of small-molecule organic solar cells with the required efficiency depends on the information obtained from molecular-level studies. In this context, 39 small-molecule donors featuring isoindigo as an acceptor moiety have been meticulously crafted for potential applications in bulk heterojunction organic solar cells. These molecules follow the D2 -A-D1 -A-D2 and D2 -A-π-D1 -π-A-D2 framework. Similar molecules considered in the previous experimental study (molecules R1 ((3 E ,3″ E )-6,6″-(benzo[1,2- b :4,5- b ']dithiophene-2,6-diyl)bis(1,1'-dimethyl-[3,3'-biindolinylidene]-2,2'-dione)) and R2 ((3 E ,3″ E )-6,6″-(4,8-dimethoxybenzo[1,2- b :4,5- b ']dithiophene-2,6-diyl)bis(1,1'-dimethyl-[3,3'-biindolinylidene]-2,2'-dione))) have been chosen as reference molecules...
