dipeptides to form 1 : 2 host–guest complexes with high binding affinity (>1010 M−2), especially up to ∼1014 M−2 for TrpTrp. Given the dynamic rotational conformation of TPE units, achiral 1 can exhibit chiral adaptive responses with mirror-symmetrical circular dichroism (CD) and circularly polarized luminescence (CPL) spectra to enantiomeric dipeptides via supramolecular chirality transfer in the host–guest
