Table 1. Zn-Ce₆ fluorescence lifetimes, τ, k_ET, and estimated E1 and ΔG⁰ values for some Zn-Ce₆–I17C–quinone complexes.

Quinone	τ, ns	k_ET, s^-1	E1, mV	ΔG⁰, eV
None	3.01	—	—	—
CoQ₀	2.42	8.1 × 10⁷	-30	-0.78
CoQ₀ reduced	3.07	0	—	—
DCBQ	2.50	6.8 × 10⁷	+470	-1.28
pBQ	2.47	7.3 × 10⁷	+99	-0.91
2,5-DMBQ	1.97	1.8 × 10⁸	-66	-0.74
2,6-DMBQ	2.18	1.3 × 10⁸	-88	-0.73

k_ET values were calculated from the fluorescence lifetime by k_ET = τ^-1 (Zn-Ce₆-I17C-quinone) - τ^-1 (Zn-Ce₆-I17C). E1 values are for parent quinones in water at pH 7 and were taken from ref. 40 or (for CoQ₀) described in the text. DCBQ, 2,6-dichloro-1,4-benzoquinine; DMBQ, dimethyl-1,4-benzoquinone.
