The invention relates to the use of compounds having at least one 2- (1-H-tetrazol- 5-yl) -pyridine pattern of the following formula (I), as lanthanide ligands, and more particularly as organic chromophores for complexing these elements. The invention also relates to lanthanide complexes using these compounds as complexing organic chromophores, and to novel compounds with a 2- (l-H-tetrazol-5-yl) - pyridine pattern(s) which are useful as lanthanide ligands, and more particularly as organic chromophores for complexing these elements. The invention can be used in photonics and opto-electronics, in particular for forming light-emitting devices such as LEDs, and in biology, e.g. for preparing luminescent probes. |
