Figure 7: Dielectric-induced stabilization of the charge transfer state.
From: An insight into non-emissive excited states in conjugated polymers
The graph (center) indicates the energy levels vs. dielectric constant of the ten lowest excited states, plotted relative to the lowest exciton-type state, for a single ground state configuration of the dimer system. Points are colored according to δq(1), the excess charge on one molecule. The lowest energy CT-type and exciton-type states are plotted with solid points. The panels on the left and right contain atomistic renderings of the system at the indicated value of the dielectric constant. The spatial distribution of excess electron and hole represented with semi-transparent red and blue spheres.
