Equilibrium constants for HBD-coupled ET determined by CV.^a

HBD[a]	K1Q•– (M−1)b	K1Q•–K2Q•– (M−2)
1	(3.4 × 104)	6.1 × 108
2	(3.5 × 105)	1.8 × 1010
3	(5.6 × 104)	1.0 × 107
4	9.2 × 1010	--
5	5.7 × 105	--

^[a]Parameters were determined by titrating 0.5 mM Q in 0.1 M nBu₄NBArF₂₄/CH₂Cl₂ (glovebox) with [HBD] and simulating the experimental CVs obtained.

^[b]Values for K_1Q•– in parentheses are thermodynamically redundant and are calculated from E₁, E₂, and K_1Q.
