Abstract
The present invention relates to luminescent lanthanide complexes including a chelating agent, formed with a macrocycle or a set of ligands, complexing a lanthanide ion Ln3+, wherein the chelating agent is substituted with at least two groups. The invention is most particularly applied to lanthanide complexes, the chelating agent of which is formed the with three ligands integrating a 2,6 pyridine-di(carboxylic acid) or is formed with a macrocycle having a 1,4,7 triazacyclononane structure.
