An electrochemical sensor based on metal–organic framework–chiral ionic liquid composites for the enantiorecognition of tryptophan enantiomers

Metal organic framework–chiral ionic liquid composites Fe-CIL was first used to construct the chiral sensor, which could be used to chiral recognize tryptophan (Trp) enantiomers based on the DPV peak potential difference (Δ E p ) of l / d -Trp.
