a Absorption spectra in chloroform solution, and b normalized absorption spectra as films of Z-2IFC-F, E-2IFC-F, Z-IFC-IC-Cl and E-IFC-IC-Cl. c Energy levels diagrams of P3HT, PM6 and acceptors. Absorption changes over time of d Z-2IFC-F and e E-2IFC-F solutions with 200-equivalent nucleophilic (Nu) reagent in THF solutions. Nu reagent is ethanolamine. f Corresponding maximum absorption peak intensity ratios of the fresh solution (I0) and the aged solution (It). Absorption spectra of g Z-2IFC-F and h E-2IFC-F films under 65 W white-light LED irradiation. i Corresponding maximum absorption peak intensity ratios (It/I0) of the fresh film and the aged film.
