CA 1339746

A class of fluorescent rare earth chelates and the ligands upon which they are based whose molecular structure incorporates a plurality of substituted arylpyridine diacid units attached to a central template structure is disclosed. These ligands function as efficient energy transfer groups in fluorescent tagging reagents and tracers. The present fluorescent chelates contain a plurality of aryl-substituted pyridines arranged structurally within a single molecule such that each optimally binds to a single metal ion. Each pyridine group is structurally insulated from the others so that, in the unchelated form, each retains to some degree the properties of the single pyridine.
