Figure 1. (A) Synthesis of the chiral binol cages via imine condensation. *represents chirality factor; (B) single-crystal structure of (R)-C1, H atoms and solvents have been omitted for clarity; (C)CD spectra of C1 and (D) fluorescence spectral changes of (R)-C1 upon the addition of (1R,2R)-1,2-diaminocyclohexane and (1S,2S)-1,2-diaminocyclohexane.
