Abstract

The photophysical characterization of pyrazolyl–pyrazine Re(i) complex, shows a ¹IL and ³MLCT excited states, being just the ³MLCT able to react with trifluoroacetic acid to yield the protonated and long-lived ³ILH⁺ species. These findings make the compound a potential sensor for protons in solution in the presence of light.
