    • Alternatively, it could be stated that the phenylethynyl group destabilizes the bodipy-centered HOMO.

    • note
    • If the complex was homoleptic, the electron pairing energy would be related to the potential difference between the third and fourth reduction process. However, because the other two reduction processes are intermediate between the first and second reductions of the same ligand in 6, the 540 mV separation value, that is the difference between the first and second reduction processes, does not have an effective significance and eventually can only be considered as a high limit for the potential separation related to electron pairing. The effective electron pairing energy should be related to a significantly lower potential separation value.

    • However, because of the presence of the heavy metal, spin prohibition could not been strictly followed in 1-6 and contribution from this route cannot be totally ruled out.

    • note
    • Femtosecond transient absorption spectroscopy was complicated by photoinstability of the investigated species under the intense laser pulses used. In fact, the free ligands displaced poor photostability under these conditions, which hampered femtosecond spectroscopy investigation of L1-L6. The metal complexes 1-6 exhibited also some photostability problems in several solvents. However, in acetonitrile they were photostable enough to allow the study. Analogous photostability problems were not faced with the nanosecond apparatus, which used a less intense laser pulse.

    • 40 have been recently observed in particular Ru(II) complexes. We also report that one of the referees made some objections on the ultrafast singlet-singlet energy transfer route (b). We believe that his/her concern is essentially due to the fact that this process has only been rarely reported up to now in multicomponent species involving transition metal complexes. But the experimental results in our hands strongly point toward this interpretation, and we decided to keep it. However, we felt that the readers should know this objection.
