Transient Exciplex Formation Electron Transfer Mechanism

Figure 14

Common dependence of log𝑘_Q (top) and log (1/𝑘_Q−1/𝑘_Diff) (bottom) on Δ𝐺_Ex^∗ (obtained according to (16)) of exciplexes of thioxantone with methylbenzenes (circles) and methoxybenzenes (squares) in MeCN (according to the experimental data of Jacques et al. [39]). Lifetimes of transient exciplexes were supposed to be 10 ps for methylbenzenes and 300 ps for methoxybenzenes.
