• Eg HL was calculated from the difference between the fitted HOMO and LUMO energy values. • HOMO/LUMO: Identical donor and acceptor molecules had variable HOMO/LUMO levels from paper to paper. Thus, both previous papers from the same research group or widely accepted universal UPS measurements were utilized in place of the omitted/variable values. Furthermore, when values for Eg opt were not reported, values were extracted by extracting the absorption onset from figures using WebPlotDigitizer (). • Information about polymer molecular weight was very challenging to obtain. Mw, Mn and Đ are not consistently reported. Often, we were required to follow a trail of references through a group's publications to find the original synthesis, and assumed that the molecular weight distribution of the polymer was the same in subsequent reports. • If two of Mw, Mn and Đ were reported, the third value was calculated.
