    • Because carbene ISC rates are slow in polar solvents, we assume that the ISC rate constants in ethanol and acetonitrile (kST, 1.4 × 109) are the same. Thus, we propose that 1Fl is not in equilibrium with 3Fl in neat ethanol and the dynamics measured are those of 1Fl and not the equilibrium mixture

    • The signal of triplet fluorenylidene is very weak in dichloromethane and fluorobenzene. The spectra (Figures S4b and S5b) have been averaged 10 000 times to improve the signal-to-noise ratio.
