Fig. 7. Relative energy level diagram illustrating the influence of the energy shift of the (S₁S₀) and the CT-state in trans-Pt. (A) Energy level diagram in typical 6,6′-linked pentacene dimers. (B) Energy level diagram in trans-Pt: the (S₁S₀) state is lowered by about 0.2 eV compared to other 6,6′-linked pentacene dimers.4,12,30 Compared to cis-Pt, the lowest CT-state of trans-Pt is about 0.9 eV higher in energy.
