description Embodiments of the invention are directed to luminescent gold(III) compounds contains a bidentate ligand with at least one strong s-donating group, a method of preparation of these compounds and the use of these compounds in organic light emitting devices.. The gold (III) compounds have the chemical structure: Formular (I) wherein: X Is a nitrogen atom; Y is selected from a carbon or a nitrogen atom; A-B is a substituted or unsubstituted cyclometalating ligand (for Y=C) or diimine ligand (for Y=N); where A and B are cyclic structure derivatives; R 1and R2 are optionally substituted carbon donor ligands attached to the gold atom, with the proviso that R1 and R2 are not -CH3, -CH2SiMe3, mesityl, pentaflurophenyl, -CH2C(O)R', -CH(R)SO2CH(R)-, -C6H4N=NC6H5, and wherein R1 and R2 can optionally be combined into a bidentate ligand; and n is greater or equal to zero. Cette invention concerne des composés auriques (Au trivalent) luminescents contenant un ligand bidentate avec au moins un groupe donneur s fort, un procédé de préparation de ces composés et l'utilisation de ces composés dans les dispositifs électroluminescents organiques. Les composés auriques (Au trivalent) présentent la structure chimique suivante (I) : X étant un atome d'azote ; Y un atome de carbone ou un atome d'azote ; A-B un ligand de cyclométallation (Y=C) ou un ligand diimine (Y=N) substitué ou non substitué ; A et B des dérivés de structure cyclique ; R1 et R2 des ligands donneurs de carbone éventuellement substitués et liés à l'atome d'or, à condition que R1 et R2 ne soient pas -CH3, -CH2SiMe3, mésityle, pentaflurophényle, -CH2C(O)R', -CH(R)SO2CH(R)-, -C6H4N=NC6H5, et que R1 et R2 puissent éventuellement être combinés dans un ligand bidentate ; et n supérieur ou égal à zéro.
