(a) 11B and 19F NMR spectra of all redox states of [2] with EPR (inset, g = 2.00674) and photo of [2b]1− in MeCN; (b) UV-vis spectra of [2a]0 and [2b]1− (50 mM) and [2c]2− (100 mM) in CH2Cl2; (c) XPS spectra for all redox states of [2] showing increasing B-B binding energy as redox state increases.
