| Abstract: | ![]()
A novel anion receptor2 bearing anthracene flurophore and thiourea was synthesized and identified by1H NMR, MS, IR and elemental analysis. The interaction between receptor2 and various α, ω-dicarboxylate anions was studied by fluorescence spectrum. The obtained fluorescence data indicate that 1∶1 stoichiometry complex is formed between receptor2 with diferent dicarboxylate anions through a hydrogen-bonging interaction. The selectivity of2 for recognition of different dicarboxylates deponds on chain length of the anionic species.
