摘要:A new tripodal receptor for anion sensing based on amide-pyridinium as recognition site and nitro-benzene as signaling unit was designed and successfully synthesized. This receptor showed high selectivity and strong binding affinity toward AcO(-) over the investigated anions, especially over H(2)PO(4) (-). Addition of AcO(-) induced clear color change of solution from colorless to yellow, realizing the "naked-eye" detection. UV-Vis and (1)H NMR experiments indicated the selectivity might origin from the synergistic effects arising from hydrogen bonding, electrostatic interactions and conformational change.
