A novel anion receptor 2 bearing anthracene flurophore and thiourea was synthesized and identified by 1 H NMR,MS,IR and elemental analysis. The interaction between receptor 2 and various α,ω-dicarboxylate anions was studied by fluorescence spectrum. The obtained fluorescence data indicate that 1:1 stoichiometry complex is formed between receptor 2 with diferent dicarboxylate anions through a hydrogen-bonging interaction. The selectivity of 2 for recognition of different dicarboxylates deponds on chain length of the anionic species.
