Enantioselective recognition by a highly ordered porphyrin-assembly on a chiral molecular gel

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, K-SV (L): 26.3 x 10(3) M-1; K-SV (D)-enantiomer: 7.03 x 10(3) M-1.
