Organic molecules with inverted singlet-triplet gaps

Organic molecules with inverted singlet-triplet gaps

According to Hund’s multiplicity rule, the energy of the lowest excited triplet state (T1) is always lower than that of the lowest excited singlet state (S1) in organic molecules, resulting in a positive singlet-triplet energy gap (ΔEST). Therefore, the up-converted reverse intersystem crossing (RIS...
