Enantioselective recognition of amino acids was achieved by using a highly ordered chiral assembly of achiral porphyrin on a chiral molecular gel. Exceptionally high enantioselectivity was observed for histidine derivatives by monitoring the CD patterns and fluorescence quenching, KSV (L): 26.3 × 103 M−1; KSV(D)-enantiomer: 7.03 × 103 M−1.
