In line with previous reports for the bimetallic photocatalysts tbbpyRuPt and fbpyRuPt, we assign the latter feature to ligand-to-metal charge-transfer (LMCT) transitions that stem from both, phenanthroline-(phen) and phenazine (phz) centered states (MLCT phen and MLCT phz ). The ESA band at 600 nm is typically associated with transitions localized on a phz centered radical anion, i.e., a MLCT phz state. This is supported by TD-DFT simulations, predicting ligand centered absorption for the MLCT phz minimum state of prbimRuPt, where electron density is shifted from the phz-to the phen-units of the tpphz ligand at 571 nm (T20, see CDD in Figure ).
