Two-Dimensional Free Energy Surfaces for Electron Transfer Reactions in Solution

Table 1

Parameters 𝑅₀ and 𝑘₀ determined by analyzing the fluorescence decay curves.

	𝐸𝑓∞/eV	−Δ𝐺^AN/eV	𝑅0/Å	𝑘0/s−1
C153-TMPD(0.2 M)	0.92	0.78	11.1	2.9×10^10
C522-TMPD(0.2 M)	0.81	0.89	12.2	3.7×10^10
C152-TMPD(0.2 M)	0.63	1.07	15.2	4.2×10^8

𝐸_𝑓∞ was calculated from Δ𝐺^AN using (4). 𝜀_𝑆=𝜀_op=2.16 for liquid paraffin and 𝑎=3.5 Å  for TMPD and 𝑏=3.9 Å  for coumarins.
