Synthesis of novel arylhydrazide molecular tweezer artificial receptors based on deoxycholic acid using microwave irradiation

摘要

Eleven novel molecular tweezer anion receptors based on deoxycholic acid have been synthesised using microwave irradiation. Their structures were established by 1H NMR, IR, MS spectra and elemental analysis. Their binding properties were examined by UV-Vis spectra titration. The preliminary results indicate that these molecular tweezers show good recognition properties for H_2PO_4-, CH_3COO- and NO_3-.
