    • Because of the different percentage of the bodipy luminescence quantum yield reduction and lifetime shortening on passing from model species to 4 at room temperature, such effects cannot be safely attributed to an intercomponent quenching process. Increased spin-orbit coupling induced by the presence of the heavy metal could also accelerate intersystem crossing within the bodipy dye. On these bases, at a first approximation here we consider intercomponent quenching processes ineffective for the decay of the bodipy singlet state, also at room temperature There are several reports of charge-separated states which collapse to lower-lying triplet states in multichromophoric species.

    • 1MLCT bands in 4 are expected to be slightly different than the sum of the individual separated components, on the basis of comparisons of the spectra of 1, 3, and 4 in Fig. 2. This, together with experimental uncertainty of the quantum yield (20%) can justify the difference (50% vs. 28%) in the theoretical and experimental reduction of emission quantum yields of singlet bodipy emission on passing from 510 to 435 nm excitation
