Fig. 2

a–c Schematic representation of the charge-transfer interactions and stoichiometric ratios between Pe[3] and TCNB in MCCs. d Crystal structure of Pe-TCNB. e–h Stacking modes of three MCCs and Pe-TCNB co-crystals in a 2D plane. Hydrogen atoms and solvents are omitted for clarity. Different colors represent symmetry equivalence. Crystallographically distinct TCNB molecules were marked as TCNB-1, TCNB-2, TCNB-3, and TCNB-4. The arrows represent π···π distances (Å) and the dashed lines represent dihedral angles.
