Abstract
A series of molecular tweezer metal receptors based on [1,2,3-triazolo-acetyl]esters of methyl deoxycholate have been synthesised via the 3,12-azidoester using a click chemistry method. Their structures were characterized by 1H NMR, IR, MS spectra and elemental analysis. Their binding properties were examined by UV-Vis spectra titration. The preliminary results indicate that this type of molecular tweezers have good recognition for metal ions.
