Luminescent gold (III) compounds containing bidentate ligands for organic light elements and their manufacturing site

摘要

Embodiments of the invention are directed to luminescent gold (III) compounds which contain a bidentate ligand with at least one strong σ donor group, a process for the preparation of these compounds and the use of these compounds in organic lighting elements. The gold (III) compounds have the chemical structure: wherein: K is a nitrogen atom, Y is selected from a carbon or a nitrogen atom, AB is a substituted or unsubstituted cyclometalate ligand (for Y = C) or diimine ligand (for Y = N ), where A and B are cyclic structural derivatives, R1 and R2 are optionally substituted carbon donor ligands attached to the gold atom, provided that R1 and R2 are not -CH3, -CH2SiMe3, mesityl, pentafluorophenyl, -CH2C (O) R ', -CH (R) SO2CH (R) -, -C6H4N = NC6H5, and wherein R1 and R2 can optionally be combined to form a bidentate ligand, and n is greater than or equal to zero
