Engineering a cationic supramolecular charge switch for facile amino acids enantiodiscrimination based on extended-gate field effect transistors
文献摘要：
Chiral recognition of essential amino acids(EAAs)is a huge challenge that keeps plaguing analyti-cal scientists due to their cryptochirality and limited steric interaction sites.Inspired by the superior enantioselectivity of functional supramolecular cyclodextrins(CDs)and strong signal amplification abil-ity of field effect transistors(FETs),this work firstly reports a cationic supramolecular charge switch for facile enantiodiscrimination of EAAs based on extended-gate organic FET(EG-OFET).The cationic phenylcarbamoylated-CD single isomer acts as a charge switch via interacting with different enantiomers and the weak stereo-differentiation intermolecular interaction signals between the cationic perphenylcar-bamoylated CDs and EAAs on the EG can be strongly and rapidly amplified through an OFET.Efficient chiral differentiation of six EAAs,including phenylalanine,tryptophan,leucine,isoleucine,lysine and va-line,are successfully achieved without any derivation process and the detection limit for D-phenylalanine is down to 10-13 mol/L.We believe that this study provides a new and facile sensing perspective for natural amino acids and may afford deeper understanding of molecular chirality.
