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

摘要

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 × 10~3 M~(-1); K_(SV) (D)-enantiomer: 7.03 × 10~3 M~(-1).
