A novel type of molecular tweezers with different chiral center and cleft has been designed and prepared by using α-hyodeoxycholic acid as spacer and d/l-amino acid methyl ester as chiral arm attached at 3-position. Their structures were elucidated by 1 H NMR, FTIR and elemental analysis. Their recognition properties for various d/l-amino acid methyl esters were also investigated. The preliminary...
A novel type of molecular tweezer receptors based on deoxycholic acid has been designed and synthesized and their binding properties were examined by UV–vis spectral titration. These molecular tweezers showed a high selectivity toward F − over Cl − , Br − , I − , AcO − , H 2 PO 4− .
