Figure 7. (A) Self-assembly of enantiopure cages C8 and C9, crystal structures of Δ-C8 and CD spectra of cages; (B) steroid guests investigated for binding with Δ-C8 and Λ-C8; (C) host-guest complexations of the enantiomers of C8 with SP and ESP; and (D) crystal structure of SP⸦Δ-C8. CD: Circular dichroism; SP: spironolactone; ESP: epimer of spironolactone.
