2-(Pyridin-2-yl)quinazolin-4(3H)-one derivatives as new ligands for lanthanide(iii) cations

A facile synthetic approach is reported toward ligands based on 2-(2-pyridyl)quinazoline, which are suitable for the preparation of both water-soluble and liposoluble chelate complexes with lanthanide(iii) cations. The ligands contain an additional rigid chelating moiety, such as the carboxyl group or the diethylenetriaminetetraacetic acid residue. The luminescence properties of the new cationic Eu^III and Tb^III complexes were studied.
