Abstract :
This paper describes the results from ultraviolet (UV) spectroscopic studies of diamide ligands namely N,N’-2,6- bis(3-pyridylmethyl)pyridine dicarboxamide (L5) and N,N’-2,6-bis(4-pyridylmethyl)pyridine dicarboxamide (L6) towards chloride, nitrate and chromate anions in solution. The responses of the ligands towards anions are monitored by the changes of the absorbance in the UV spectra. The time interval experiments were conducted from 0 to 3 hours, resulted to the rise of the absorbance of the ligands. The change in the absorbance value is attributed to the increase of interaction between the ligands and anions that is proportional with time. In contrast to the ligands, the absorbance of anion is decreased showing the reduction of anion concentration in the solution. Rapid UV response indicates the sensitivity of these ligands towards anions which at the same time showing promising potential as sensitive anion sensor.
