Abstract
A series of novel chiral di-imidazolium tweezers were synthesized from L-alanine and L-phenylalanine. These compounds featured two open arms and multipoint binding sites. UV spectroscopic titration experiments showed these chiral di-imidazolium receptors exhibited excellent enantioselective recognition toward L- and D-amino acid derivatives in water or acetonitrile.
Keywords: UV-vis, enantioselective recognition, synthesis, molecular tweezers, Chiral imidazolium
