“…In the present work, we introduce a versatile, rapid and low‐cost strategy to measure the photocatalytic activity of photosensitizers based on redox cycling of HQ as an electroactive mediator (Figure ). HQ is an effective scavenger of singlet oxygen ( 1 O 2 ), and hydroxyl radical (HO . ), which is yet inert towards superoxide (O 2 .− ) and moderate amounts of H 2 O 2 .…”

“…Moreover, probes such as 9,10‐anthracenedipropionic acid (ADPA), 2,2,6,6‐tetramethylpiperidine (TEMP), furfuryl alcohol (FFA) and 1,3‐diphenylisobenzofuran (DPBF) are also widely used for indirect detection of 1 O 2. [33] Our recent work resolved one of the major gaps in the literature, providing improved kinetic information on TEMP‐trapped singlet oxygen against a theoretical model [148] . The strictly hindered amine (i. e., TEMP) reacts selectively with singlet oxygen to form nitroxide radical (TEMPO) that displays a the EPR signals (Figure 12, LHS) that enabled the quantitative validation of our POLYMATH‐based kinetic model in Figure 12, RHS [148] …”

“… Time course signal of TEMPO (product of the reaction of singlet oxygen and TEMP) in H 2 O (red circles) and D 2 O (black squares); TEMPO spectra recorded by in situ EPR after illuminating TEMP sample in dyed D 2 O solution at pD=6.35, g=2.00062, and centre field=3487.00 G; and EPR concentration profile of singlet oxygen generated in H 2 O using 24 V LED. The dash‐dotted line represents the corresponding values obtained from the POLYMATH kinetic solution [148] …”
