| Abstract: | A novel type of chiral molecular tweezers has been designed and synthesized by using beteroaromatics as spacer and chiral unsymmetrical urea as arm. Their structures were identified by lH NMR, IR, MS spectra and elemental analysis. The recognition properties of these new receptors for halide anions have been investigated by UV-visible spectral titration. The preliminary results showed that all these molecular tweezers possessed the ability to form complex with anion examined. The greatest association constant reached 14270 Lomol^-1. |
