The invention relates to a porous material in the form of microspheres based on iridium and/or iridium oxide, its preparation process, its use as anodic catalyst in a water electrolyser based on a solid polymer electrolyte, also called PEM water electrolyser (with PEM meaning 'Proton Exchange Membrane' or 'Polymer Electrolyte Membrane') or for the manufacture of light-emitting diodes for various electronic devices or for cars, and a PEM water electrolyser comprising such a material as an anode catalyst.

Iridium and / or iridium oxide microsphere-based porous material, preparation method therefor, and uses thereof

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.
