Understanding and tuning singlet–triplet (S1–T1) energy gaps in planar organic chromophores

Molecules with large gaps between their first singlet and triplet excited states (ΔEST) are key components of various modern technologies, most prominently singlet fission photovoltaics and triplet–triplet annihilation upconversion (TTA-UC). The design of these molecules is hampered by the fact that...
