Of the organic PCs discussed, only PTH has been proposed to dehalogenate aryl halides through an oxidative quenching cycle, this based on Stern-Volmer quenching studies that showed only iodobenzene could quench the emission of PTH, while no discernible quenching was observed with NBu3. However, the excited state oxidation potential, E*ox, of PTH is quoted as -2.10 V vs SCE, yet PTH was shown to dehalogenate 2-bromophenyl (Ered = -2.58 V vs SCE), a transformation which would be considerably endergonic. PDI, [ t Bu-Mes-Acr]BF4 and 3CzEPAIPN (and related derivatives) have all been suggested to operate via the conPET mechanism. The evidence to support this stems from the quadratic dependency of yield with light irradiation intensity, and the direct detection of PC •-, by EPR spectroscopy, as an intermediate in the photocatlysis. Despite the advances that have been made in the photoinduced dehalogenation of aryl halides, the reaction conditions employed often use high organic PC loading (5-10 mol%) and multiple light sources. As part of a larger research effort devoted to the design of highly photooxidizing and photoreducing PCs, we sought to demonstrate the utility of a new family of donor-acceptor TADF compounds as PCs that would be capable of promoting the photoinduced dehalogenation of aryl halides under milder reaction conditions. TADF compounds have received steadily increasing interest for their use as PCs, particularly 4CzIPN which has been documented as a PC in >600 literature reports. TADF compounds are typically composed of donor and acceptor units that are electronically weakly coupled, usually due to a strongly twisted conformation. Thus, modifications of the donor and acceptor motifs adjust the HOMO and LUMO levels, respectively, facilitating a facile tuning of the optoelectronic properties of the compounds. With this in mind, we focused on 10-(4-(4,6-diphenyl-1,3,5-triazin-2-yl)phenyl)-9,9-dimethyl-9,10-dihydroacridine, DMAC-TRZ (Figure ). First developed in 2015 as a sky-blue emitter for organic light-emitting devices, DMAC-TRZ is composed of a DMAC donor connected to a triazine acceptor. We identified DMAC-TRZ as a potentially useful photoreductant as it has a moderate optical gap (E0,0 = 2.50 eV in DMF), and ground-state oxidation potential (Eox = 0.97 V vs SCE in DMF), leading
