WebApproach 1 is marked by the formation of complexes in two steps, the first of which refers to the coordination of europium(III) by COOH or PHEN ligands. The presence of broad excitation bands (π → π*) below de 325 nm [28] confirms the antenna capacity of the PHEN ligand in the SNP 50-PHEN sample. The parent of this family of ligands is the amino acid glycine, H2NCH2COOH, in which the amino group, NH2, is separated from the carboxyl group, COO>H by a single methylene group, CH2. When the carboxyl group is deprotonated the glycinate ion can function as a bidentate ligand, binding the metal centre through the nitrogen and one of two carboxylate oxygen atoms, to form chelate comple…
