摘要：A simple pincer-shape anion receptor L1 containing amide-pyridinium as binding unit was synthesized and its anion binding properties were investigated by UV-Vis, NMR titration spectra and molecular simulation. L1 displayed better affinity toward AcO- ion with visible color change compared with other investigated anions, including F-, H2PO4 (-), Cl-, Br-, I-, NO3 (-) and HSO4 (-) ions. The selectivity was ascribed to the synergistic effects arising from hydrogen bonding, electrostatic interaction and induced-fit process.
