An oxalamide-bridged imidazole based ‘turn off’ fluorescent receptor for copper( ii ) and iron( iii ) ions

We describe the synthesis of a symmetrical N , N ′-bis(3-(1 H -imidazol-1-yl)propyl)oxalamide-based receptor OX(PID) 2 and its characterization by different physicochemical techniques, namely FT-IR, 1 H and 13 C NMR, TGA, and mass spectrometry.
