Abstract：The interactions of N-aryl-N′-(4-ethyloxybenzoyl) thioureas derivatives and anions such as F-,Cl-,Br-,I-,CH3COO-,H2PO-4,HSO-4 and NO-3 in DMSO were investigated by UV-Vis and 1H NMR spectroscopy. The results showed that hydrogen-bonding complexes were formed between receptors and the three anions such as F-,CH3COO- and H2PO-4,and the solutions turned light yellow from colorlessness, but there had no evident binding with Cl-,Br-,I-,HSO-4 and NO-3. It was regular that the two receptors had different binding ability with F-,CH3COO- and H2PO-4. For the same anion, the association constants followed the trend: receptor 1a> receptor 1b. The UV-Vis data indicated that a 1∶1 stoichiometry complex was formed.
