Abstract
2-N-anilinopyrimidine was used as specific binder towards selected transition metals ion such as Mn(II), Ni(II) and Cr(II) in a 1 : 2 ratio ( metal : ligand ) to give their respective complexes. The structures of the ligand and complexes were confirmed by spectroscopic analysis. Fluorescence studies of metal complexes of 2-N-anilinopyrimidine and the ligand itself were carried out under various conditions using methanol as the solvent. In general, metal ions, especially paramagnetic ions, are able to quench the fluorescence of organic ligands. The fluorescence intensity was studied based on several factors such as pH, capped and uncapped conditions. The compounds showed higher intensity in capped samples compared to uncapped samples.
Keywords: 2-N-anilinopyrimidine, fluorescence, metal complexes, pH effect, capped samples, uncapped samples
