The invention relates to the use of compounds comprising at least one 2-(1H-tetrazol-5-yl)pyridine unit, of formula (I) below:
as ligands for lanthanides and, more especially, as organic chromophores for complexing these elements.
It also relates to lanthanide complexes using these compounds as complexing organic chromophores, and to new compounds containing one or more 2-(1H-tetrazol-5-yl)pyridine units, which are useful as ligands for lanthanides and, in particular, as organic chromophores for complexing these elements.
Applications: photonics and optoelectronics, especially for forming light-emitting devices such as electroluminescent diodes; biology, as for example for the preparation of luminescent probes.

L'invention se rapporte à l'utilisation de composés comprenant au moins un motif 2- (1-H-tétrazol- 5-yl) -pyridine, de Formule (I) ci-après : comme ligands des lanthanides et, plus spécialement, comme chromophores organiques de complexation de ces éléments. Elle se rapporte également à des complexes de lanthanides utilisant ces composés comme chromophores organiques de complexation, ainsi qu'à de nouveaux composés à motif (s) 2- (l-H-tétrazol-5-yl) - pyridine, utiles comme ligands des lanthanides et, en particulier, comme chromophores organiques de complexation de ces éléments. Applications : photonique et opto¬ électronique, notamment pour la formation de dispositifs d'émission de lumière comme des diodes électroluminescentes; biologie, par exemple pour la préparation de sondes luminescentes.
Remarkable Tuning of the Coordination and Photophysical Properties of Lanthanide Ions in a Series of Tetrazole-Based Complexes
bipyridine‐based (25 nm) complexes towards the visible region (up to 440 nm). Moreover, the substitution of the terpyridine–tetrazolate system with different groups in the ligand series L3–L6 has a very important effect on both absorption spectra and luminescence efficiency of their lanthanidecomplexes. The tetrazole‐based ligands L1 and L3–L8 sensitize efficiently the luminescent emission of lanthanide ions in the
