Neutral anion receptors play an important role in nature. For this reason, artificial
neutral receptors became an attractive target for studies. Therefore, in this study, four
new amide compounds were synthesized from reactions between 2,6-dimethylpyridine
dicarboxylate and 2-amino-4-methylpyridine . The synthesized ligands were
characterized by using spectroscopy methods such as Fourier Transform infrared (FT-
IR), nuclear magnetic resonance spectroscopy (NMR) and ultraviolet-visible (UV-Vis)
spectroscopy. The infrared analysis showed the presence of four significant peaks for
νstr(N-H), νstr(C-H), ν(C=O), νbend(N-H) and at range of 3274-3452 cm−¹, 2812-
2968 cm−¹, 1686-1742 cm−¹, and 1533-1571 cm−¹, respectively. While for 1 H NMR
results, the presence of N-H were indicated at range of δH = 10.30-10.41, respectively.
The UV spectra indicated the absorbance for C=O group and pyridine group. The anion
binding studies of the ligands toward chromate were monitored by UV spectroscopy
and the results show promising potential as chromate receptor.
