Abstract:

Three aromatic oligosulfonate-bridged macrocyclic compounds were synthesized using 4,6-dialkoxy-benzene-1,3- disulfonyl dichlorides and aromatic diphenol as the starting materials, triethylamine as the acid binding agent, and dichloromethane as the solvent. The products were characterized by IR, 1H NMR, 13C NMR, MALDI-TOF techniques. The recognition capabilities of aromatic oligosulfonate-bridged macrocyclic compound 5 for 20 metal ions were studied by UV spectroscopy. Compound 5 has certain recognition abilities for Sn2+. If Bi3+ solution is added into compound 5 and Sn2+ system, the absorption peak at 325 nm increases greatly in UV spectroscopy because of the synergy effect of Sn2+ and Bi3+, suggesting that compound 5 has better recognition ability for Bi3+ than that for Sn2+.
