The present invention includes a series of novel osmium bis(tridenatate) complexes with emission profiles in the near-infrared region.

Organic electroluminescent materials and devices

The present invention includes novel compounds having a boron containing ring for use as charge transporters, hosts or emitters in OLEDs.

Novel metal compounds having a first ligand Lthat has the following formula: Formula I useful as emitters in OLED application are disclosed.

This invention relates to the development of heterocyclic materials for use as blue phosphorescent materials in OLED devices. The materials are based on a pair of 5-membered aromatic or psuedoaromatic rings bonded to one another and complexed to a transition metal. The materials were determined computationally to have appropriate triplet energies for use as blue emitters and to possess sufficient chemical stability for use in devices.

A compound having the formula Ir(L)(L), having the structure Formula I, is disclosed. In Formula I, each of Z, Z, Z, and Zis CR; X is O, S, or Se; n is an integer from 1 to 3; R, R, R, R, and Reach independently represent mono- to a maximum possible number of substitutions, or no substitution; R, R, R, R, and Rare each independently selected from a variety of substituents; any two substitutions in R, R, R, R, and Rare optionally joined to form a ring; at least one pair of substitutions in R, R, R, R, and Rare joined together to form a bridge structure comprising a backbone structure that forms a fused first ring, which can be further substituted; and the backbone structure is saturated. Organic light emitting devices and consumer products containing the compounds are also disclosed.

The present invention includes novel heterocyclic materials for use as blue phosphorescent materials in OLED devices. The materials are based on carbene and heterocyclic 5-membered ring linked ligands, which may be complexed to a transition metal via a metal-carbon (carbene) bond and a metal-nitrogen covalent bond. In one aspect, the present invention provides compounds comprising a ligand Lhaving the structure of Formula I: 

A compound comprising a ligand Lhaving the formula: is disclosed.Such a compound is suitable for use an emitter in organic light emitting devices.

The present invention includes novel heterocyclic materials for use as blue phosphorescent materials in OLED devices. The novel materials include two fused 5-membered aromatic or pseudoaromatic rings, which are bonded with 6 membered aromatic rings to serve as chelation ligands for a transition metal. The novel materials were determined computationally to have appropriate triplet energies for use as blue emitters and to possess sufficient chemical stability for use in devices.

This invention relates to the development of heterocyclic materials for use as red, green, and blue phosphorescent materials in OLED devices. The materials are based in part on a pair of aromatic or psuedoaromatic rings bonded to one another and complexed to a transition metal. Azaborinane, borazine, and related aromatic structures including boron may be incorporated as fused rings, as pendant groups, or as bridging groups to tune color and improve chemical stability. Desirable structures may be selected by being determined computationally to have appropriate triplet energies for use as blue emitters and to possess sufficient chemical stability for use in devices.

A compound having the formula Ir(L)(L), having the structure, Formula I, is disclosed. In Formula I, Z, Z, Z, and Zeach independently are N or CR; X is O, S, or Se; n is an integer from 1 to 3; R, R, R, R, and Reach independently represent mono- to a maximum possible number of substitutions, or no substitution; R, R, R, R, and Rare each independently selected from a variety of substituents; any two substitutions in R, R, R, R, and Rare optionally joined to form a ring; at least one pair of substitutions in R, R, R, R, and Rare joined together to form a bridge structure comprising a backbone structure that forms a fused first ring, which can be further substituted; and the backbone structure is saturated.
