Provided are photochromic optical articles including an optical substrate and an at least partial anisotropic layer disposed on the at least a portion of the surface of the substrate. The anisotropic layer includes an anisotropic polymer; a photochromic-dichroic dye, a photochromic dye, or combination thereof; a mesogenic hindered amine light stabilizer; and a mesogenic antioxidant. Provided are photochromic coated articles including a substrate and an anisotropic coating layer on at least a portion of the surface of the substrate. The anisotropic coating layer is formed from a polymerizable composition including a polymerizable anisotropic material; a photochromic-dichroic dye, a photochromic dye, or combination thereof; a mesogenic hindered amine light stabilizer; and a mesogenic antioxidant.

An organic light emitting device, comprising: an anode, a hole transport layer; an organic emissive layer comprising an emissive layer host and an emissive dopant; an electron impeding layer, and electron transport layer, and a cathode disposed, in that order, over a substrate.

Organic electroluminescent materials and devices

Organic light emitting materials and devices comprising phosphorescent metal complexes comprising ligands comprising aryl or heteroaryl groups substituted at both ortho positions are described. An organic light emitting device, comprising: an anode, a hole transport layer; an organic emissive layer comprising an emissive layer host and an emissive dopant; an electron impeding layer; and electron transport layer; and a cathode disposed, in that order, over a substrate.

Stability OLED materials and devices

Compounds comprising phosphorescent metal complexes comprising cyclometallated ligands having a structure of In the vgs3, each of the Eatoms is selected from C and N, except that Eis selected from C, N, and S. The Eatoms collectively comprise an 18 pi-electron system, provided that Eand Eare different. The Rsubstituents are each, independently, H, hydrocarbyl, heteroatom substituted hydrocarbyl, cyano, fluoro, OR, SR, NRR, BRR, or SiRRR, where the Rsubstituents are each, independently, hydrocarbyl or heteroatom substituted hydrocarbyl. Any of the Ror Rsubstituents can be linked to form a saturated or unsaturated, aromatic or non-aromatic ring, provided that the Rsubstituents are not present when the corresponding one of E atoms is N or S. Organic light emitting diode devices comprising these compounds are also described.

Compounds comprising phosphorescent metal complexes comprising cyclometallated imidazo[1,2-f]phenanthridine and diimidazo[1,2-a:1',2&#x2032;-c]quinazoline ligands, or isoelectronic or benzannulated analogs thereof, are described. Organic light emitting diode devices comprising these compounds are also described.

Compounds that have ultraviolet light absorbing properties, and which can also have mesogenic properties. Compositions that include one or more such compounds. Articles of manufacture that include one or more such compounds, such as optical elements that include an optical substrate and a layer that includes at least one such compound.

Ultraviolet light absorbers

A multilayer photochromic article can include a photochromic substrate, which may include a first photochromic layer defining a surface of the substrate, and a second photochromic layer positioned between the surface of the photochromic substrate and a source of actinic radiation, and in which the photochromic substrate and the second photochromic layer are selected such that the fade half-life of the photochromic substrate or the half-life of the first photochromic layer defining the surface of the substrate are greater than the fade half-life of the second photochromic layer.
