FMOs and FMOLs of the anthracene–TCNE systems with two different configurations: the double bond in TCNE is perpendicular to anthracene (V configuration) and parallel with anthracene (P configuration). (a) HOMO, (b) LUMO, (c) HOMOL, and (d) LUMOL of the P configuration; (e) HOMO, (f) LUMO, (g) HOMOL, and (h) LUMOL of the V configuration. FMOs perform better in the description of the CT character in the V configuration than in the P configuration. FMOLs further improve the description of the CT character in the P configuration by locating HOMOL on the donor molecule and LUMOL on the acceptor molecule. Iso = 0.02.
