Transient Exciplex Formation Electron Transfer Mechanism

Figure 10

Dependences of log𝑘_Q (top) and log (1/𝑘_Q−1/𝑘_Diff) (bottom) on Δ𝐺_ET^∗ for quenching of excited singlet states of various aromatic compounds by chlorobenzenes in MeCN (according to the experimental data of Grosso et al. [12]). Best plots are shown for simulation of the experimental dependence by (3) (𝜆=0.7 eV) (dash line) and by concatenated mechanism (16) (solid line). Dotted line shows thermodynamic limit for ET.
