Luminescent gold(III) compounds containing bidentate ligand for organic light-emitting devices and their preparation

摘要

Embodiments of the invention are directed to luminescent gold(III) compounds containing a bidentate ligand with at least one strong -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: 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 YC) or diimine ligand (for YN); where A and B are cyclic structure derivatives; R1 and R2 are optionally substituted carbon donor ligands attached to the gold atom, with the proviso that R1 and R2 are not —CH3, —CH2SiMe3, mesityl, pentafluorophenyl, —CH2C(O)R′, —CH(R)SO2CH(R)—, —C6H4NNC6H5, and wherein R1 and R2 can optionally be combined into a bidentate ligand; and n is greater or equal to zero.
