Organic electroluminescent materials and devices

A compound comprising a ligand Lcomprising a moiety L having a structure of Formula I is provided. In Formula I, Lcoordinated to a metal M; Ais selected from B, N, P, P═O, P═S, Al, Ga, SiR″, GeR″, and SnR″; where rings A, B, and C are 5- or 6-membered rings; Y, Y, and Yare selected from direct bonds, the metal M, and a variety of linkers; a+b+c=2 or 3; and one of a number of specific conditions is met. OLED devices, consumer products, and formulations including the compound are also provided.

A compound having a structure of Formula I, is provided. In Formula I, Zto Zare each CR or N; three consecutive ones of Zto Zwithin the same ring cannot be N; each R is independently a hydrogen or a substituent selected from a variety of substituents; at least one R includes and electron donor substituent; at least one R includes an electron acceptor substituent; and any two Rs on the same ring can be joined or fused together to form a ring. Organic light emitting devices, consumer products, formulations, and chemical structures containing the compounds are also disclosed.

A compound of the following Formula I is provided. In Formula I, A is C, B, Si, Ge, or Sn; each of Xto Xis independently C or N; Zand Zare each independently B or N; when A is B, one of X, X, X, and Xis N, and the remainder are C; when A is C, at least one of Zand Zis B; each of Y, Y, Y, and Yis independently O, S, Se, NR, CRR', SiRR′, GeRR′, and SnRR′; one of both of Yand Yare present; one of both of Yand Yare present; each R, R′, R, R, R, R, R, and Ris independently hydrogen or a variety of substituents; and any two adjacent R, R′, R, R, R, R, R, and Rcan be joined or fused to form a ring. Devices, consumer products, and formulations including the compound are also disclosed.

Provided are compounds comprising a ligand Lof Formula I where the ligand Lis coordinated to Ir.

Provided are novel C-symmetry high Tenergy host compounds. Also provided are formulations comprising these novel C-symmetry high Tenergy host compounds. Further provided are OLEDs and related consumer products that utilize these novel C-symmetry high Tenergy host compounds. The novel host compounds are represented by where the variables are defined herein.

This invention relates to the development of heterocyclic materials with high triplet excitation energy, which can be used as host materials in electroluminescent devices such as a PHOLED. The materials improve the performance of such devices by enhancing the lifetime and efficiency of the device when the newly developed heterocyclic materials are utilized as a host.

Host materials for electroluminescent devices

The present invention includes novel compounds containing deuterated or partially deuterated xanthene and thioxanthene structures. These compounds may be useful as host materials with high triplet energies for phosphorescent electroluminescent devices.

Provided are compounds comprising a ligand Lof Formula I
