Fig. S1. 2D NOESY spectrum of F-P-F recorded in CDCl 3 at room temperature. Fig. S2. OSWVs (cathodic and anodic scans) of compound F on a Pt electrode in CH 2 Cl 2 + 0.1 M nbu 4 NBF 4 at room temperature. Fig. S3. OSWVs (cathodic and anodic scans) of compound 12 on a Pt electrode in CH 2 Cl 2 + 0.1 M nbu 4 NBF 4 at room temperature. Fig. S4. Corrected singlet oxygen luminescence spectra of air-equilibrated solution containing P (black), F (gray) and F-P-F (light gray). a) toluene: λ exc = 550 nm, A = 0.300. b) benzonitrile: λ exc = 560 nm, A = 0.300. Fig. S5. Top: differential transient absorption spectra of P (grey dots), F (grey triangles, 0.7 x 10-4 M) and F-P-F (black) obtained at 100 ns after nanosecond laser pulse per pulse irradiation at 560 nm in deaerated benzonitrile at 298 K; inset: time profile of differential transient absorption spectra for F-P- F obtained at 0-3.5 μs time intervals monitoring at 650 nm (λ exc = 560 nm). Bottom: differential transient absorption spectra of P (grey dots), F (grey triangles) and F-P-F (black) obtained at 100 ns after nanosecond laser pulse irradiation at 560 nm in deaerated toluene at 298 K; the energy of the laser used was 0.25, 1 and 2 mj per pulse for P, F and F-P-F respectively. The intensity of the signals is not directly comparable because the intensity of the laser and/or the concentration of the solution were adjusted to observe the features of charge separation in F-P-F which are intrinsically weaker than the triplet features of F and P, which also may undergo triplet triplet annihilation phenomena at high concentration or under high excitation power.
