Figure 2. (A) Synthesis of heterochiral porous organic cage C2. *represents chirality factor; CD spectra of (S,R)-C2 with different concentrations of (B) D-carvone and (C) L-carvone; (D) The CD intensity at λ = 250 nm vs. the D-carvone concentration. The CD spectra of (R,S)-C2 with various concentrations of (E) L-carvone and (F) D-carvone; (G) The CD intensity at λ = 250 nm vs. the L-carvone concentration. CD: Circular dichroism.
