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 [Sigma]-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 Y-C) Or Diimine Ligand (For Y-N); 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)-, -C6h4n-Nc6h5, And Wherein R1 And R2 Can Optionally Be Combined Into A Bidentate Ligand; And N Is Greater Or Equal To Zero.
