Transient Exciplex Formation Electron Transfer Mechanism

Figure 4

Simulation of the dependences Δ𝐺_Ex^∗ (red points) and 𝑧 (blue points) versus Δ𝐺_ET^∗, according to self-consistent polarization of the medium and exciplex ((13), (14), 𝑉=0.2 eV, 𝑚𝑓(𝜀)=0.4 eV). Approximation of Δ𝐺_Ex^∗−Δ𝐺_ET^∗ dependence (black line) by hyperbolic function (15). Dash lines show dependences of Δ𝐺_Ex^∗ and 𝑧 from Δ𝐺_ET^∗ according to the simple model of interaction of LE (𝑈_LE⁰=0+𝑎^∗) and CT (𝑈_CT⁰=Δ𝐺_ET^∗+𝑎^∗) terms.
