Remarkably, the integral ratio between the ESA (550-640 nm) and GSB (440-500 nm) for prbimRuPt (∆t = 1 ps, integral ratio: 3.1) is approximately two times greater than for tbbpyRuPt and circa six times higher than for fbpyRuPt (see Figure ). The same trend of ESA-to-GSB integral ratios is observed for the mononuclear counterparts of the three complexes (cf. Figure ).
