    • 2 ≈ 1) by a monoexponential decay function that yields lifetimes of 3.5 ± 0.5 ns (1a), 3.1 ± 0.2 ns (1b), and 2.9 ± 0.5 ns (1c). The authors would like to point out that, in the experiments in benzonitrile, much lower signal intensities (with respect to those in THF) were noted. No traces of Pc 2 contamination were found in the samples of 1a-c.

    • note
    • To confirm the intramolecular charge recombination dynamics we probed 1a-c at different laser powers and different concentrations. Regardless of the experimental conditions, the best fits were obtained by applying unimolecular decay functions that gave rise to the same charge recombination rate constants.
