Novel phosphorescent heteroleptic iridium complexes with phenylpyridine and dibenzo-containing ligands are provided. Alkyl substitution at specific positions on the ligands gives rise to compounds with improved OLED properties, including saturated green emission.

Heteroleptic iridium complexes as dopants

Organic materials containing dibenzofuran or aza-dibenzofuran moiety are disclosed in this application. These materials are expected to improve OLED device performance.

Organic electroluminescent materials and devices

A composition of materials including a first compound having a structure according to Formula I

A compound having the formula (L)Ir(L), where Lis and Lis selected from is disclosed. In the formula (L)Ir(L), Land Lare different; each of Xto Xis C&#x2014;Ror nitrogen; X is selected from O, S, and Se; each R, R, R, R, R, and Ris hydrogen or a substituent; Ris alkyl, cycloalkyl, or a combination thereof; and m is 1 or 2. OLEDs, consumer products, and formulations including the compound are also disclosed.

A composition of materials including a first compound having a structure according to Formula I 

A compound comprising a ligand Lof Formula I: as well as, devices and formulations containing the compound of Formula 1 are disclosed. In the compounds, having a ligand La of Formula I: wherein Rrepresents mono, or di-substitution, or no substitution; wherein Rrepresents di, tri, or tetra-substitution; wherein R is selected from hydrogen, deuterium, alkyl, cycloalkyl, and combinations thereof; wherein Rand Rare each independently selected from hydrogen, deuterium, alkyl, cycloalkyl, aryl, and combinations thereof; wherein at least one pair of adjacent Rsubstitutions are joined to form a fused ring; wherein the ligand Lis coordinated to a metal M; and wherein the ligand Lis optionally linked with other ligands to comprise a tridentate, tetradentate, pentadentate or hexadentate ligand.

Organic compounds consisting of indolo[321-jk]carbazole and carbazole are disclosed. The compounds are useful as host materials in OLEDs and can improve OLED performance.

A method of forming compounds that comprise a heterocyclic carbene ligand is provided. In particular, an oxazole or a thioazole carbene are used in place of the traditional imidazole carbene. These compounds may be used in OLEDs to provide devices having improved properties, such as stability and color-tuning.
