Abstract: Two synthesized compounds,N-(6-aminopyridine2-yl)-9-anthracenecarbonamide(L1) and N,N’-(pyridine-2,6-yl)-bis(9-anthracenecarbonamide)(L2) are found to show good sensitivity and selectivity to Fe3+ and Hg2+ ions,respectively.L1 shows highly sensitive response to Fe3+ on fluorescence spectrum.The recognition of L2 to Hg2+ could be achieved by using absorption and fluorescence spectra.The effect of the presence of other metal ions on sensing for the aim ions were studied too.In addition,the coordination models of these two compounds with metal ions were suggested.

Key words: anthracenecarbonamide, chemosensor, Fe3+, Hg2+, spectroscopy
