摘 要:Novel azine based receptors with phenolic hydroxyl groups have been synthesized and characterized. A remarkable color change was observed from 1H NMR and UV-Vis titrations upon the addition of fluoride ions to the solution of receptors in DMSO. The addition of chloride, bromide and iodide to the receptors did not induce any change. The UV-Vis data indicate that a 1∶1 stoichiometry complex is formed between receptors and F-. 1H NMR titrations and solvation effect confirmed hydrogen interaction between the receptors and anion. Hence, the receptors bearing phenolic hydroxyl groups can act as fluoride ion sensors even in the presence of other hahide ions.Novel azine based receptors with phenolic hydroxyl groups have been synthesized and characterized.
