摘要：

A series of colorimetric anions sensors bearing phenol OH and NH groups were synthesized. The binding properties of the receptors with anions such as F-, Cl-, Br-, I-, CH3COO-, H2PO4-, HSO4- and ClO4- in DMSO were examined by UV-Vis and H-1 NMR spectra. The results showed that these sensors had a better selectivity for F-, CH3COO- and H2PO4-, but had no evident binding with Cl-, Br-, I-, ClO4- and HSO4-. Especially, the receptor 2 in V(DMSO) : V(H2O)=-7 : 3 solutions indicated colorimetric single selectivity for CH3COO-. H-1 NMR titrations showed that there are hydrogen bonding interaction between the receptors and anions.
