摘要:
Three acylhydrazone-based receptors have been synthesized. Their anion recognition properties were studied by UV-visible and 1 H NMR spectroscopy. The results showed that the receptors 1, 2 and 3 all had a stronger complexity with F-, H(2)PO(4)(-)and CH3COO -, but no evident binding with Cl-, Br, I-, NO(3)(-)and HSO4-. Moreover, upon addition of such anions as F-, H(2)PO(4)(-)and CH3COO-, 1 and 2 produced obvious colour changes. The recognition mechanism and binding mode were discussed.
