(a) Structure of the [Re(CO)₃(dmp)]⁺ photosensitizer (dmp = 4,7-dimethylphenanthroline) attached to azurin close to the indole ring of tryptophan 122. (b) Scheme of charge transfer states after photoexcitation. (c) Temporal evolution of the electronic wave function character, with the largest contributions MLCT, IL_Dmp (intraligand excitation on dimethylphenanthroline), and CS (charge-separated, i.e., charge transfer from tryptophan to dimethylphenanthroline).
