The use of [Ru(bpy)3](PF6)2 (Eox* = -0.86 V vs SCE) as the PC has been show to yield the product in 80% in MeCN, while organic D-A TADF compounds like pDTCz-DPmS and 4CzIPN are not nearly as efficient, affording 16 and 10% of product, respectively, in DCM. The MR-TADF library in this study was tested in this reaction as the PC in different solvents, with either one or two equivalents of styrene (
