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 towardL- and D-amino acid derivatives in water or acetonitrile.
