Testing of multiple batches as well as multiple runs on the same batch confirmed the activity of the best-performing material, TT-TAB, within a 15% error margin (Figure ). These notable activities are corroborated by apparent quantum efficiencies (AQEs) at different wavelengths, which we determined for the most active material, TT-TAB. At wavelengths of 415, 460 and 490 nm, we obtained excellent AQEs of 4.48, 1.80, and 0.80%, respectively. These values are consistent with the acquired UV/Vis absorption spectrum of TT-TAB (Figure ).
