LUMINESCENT GOLD(III) COMPOUNDS CONTAINING BIDENTATE LIGAND FOR ORGANIC LIGHT-EMITTING DEVICES AND THEIR PREPARATION

Abstract

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.
