Abstract: A novel class of saturated or conjugated dendrimers containing at least one strong ?-donating group coordinated to cyclometalated tridentate gold(III) compounds having the chemical structure depicted by generic formula: wherein: (a) [Au] is a cyclometalated tridentate gold(III) group; (b) Unit A is a ?-donating chemical group; (c) Unit B is a central part of the dendrons comprising a branch point of component dendrimers; (d) Unit C is optional surface groups or dendrons of the dendrimers; (e) n=0 or 1.

Abstract: In one embodiment, the present invention provides a class of luminescent gold(III) compounds containing a tridentate ligand with one strong ?-donating group. The present invention also provides methods for synthesizing these compounds, as well as uses of these compounds as electrophosphorescent materials in phosphorescent organic light-emitting devices (OLEDs) to provide electroluminescence (EL).

Abstract: A class of luminescent gold(III) compounds containing a tridentate ligand with one strong ?-donating group having the chemical structure depicted by generic formula (I): wherein: (a) X is selected from nitrogen; (b) Y and Z selected from carbon; (c) A is cyclic structure derivative of pyridine group; (d) B and C are cyclic structure derivative of phenyl groups; (e) R1 is an optionally substituted carbon donor ligand attached to the gold atom; (f) n is zero, a positive integer or a negative integer.

Abstract: Embodiments of the invention are directed to luminescent gold(III) compounds contains 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 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.

Abstract: There are disclosed rare-earth metal containing electron-injecting electrodes which are particularly effective for use with organic LED devices used in electroluminescent structures and which may in particular be formed as transparent electrodes for use in transparent or surface emitting OLEDs.
