The present invention relates to a polymeric charge transfer layer comprising a polymer and a p-dopant. The polymer comprises as polymerized units, Monomer A, Monomer B, and Monomer C crosslinking agent. The present invention further relates to an organic electronic device, especially an organic light emitting device containing the polymeric charge transfer layer.

Polymeric charge transfer layer and organic electronic device containing the same

The present disclosure provides a composition. In an embodiment, a composition is provided and comprises a Compound 1 shown below: For Compound 1, Rthrough Rare the same or different. Rthrough Reach is independently selected from the group consisting of hydrogen, unsubstituted hydrocarbyl, substituted hydrocarbyl, cyano, alkoxy, aryloxy, and NR'. R&#x2032; is hydrogen or hydrocarbyl; wherein two or more of adjacent Rto Rmay optionally form one or more ring structures. The Component Z is selected from the group consisting Group Z-1, Group Z-2, Group Z-3, Group Z-4, Group Z-5, Group Z-6 and Group Z-7 shown below: For Compound 1, one or more hydrogen atoms may optionally be substituted with deuterium. 

Compositions with triarylamine derivatives and OLED device containing the same

Aspects of the invention provide a composition having a blend of an electron transport material and an organo alkali-metal salt wherein the salt has a glass transition greater than 115&#xb0; C. The organo-alkali metal salt may be selected from the group consisting of lithium 2-(2-pyridyl)phenolate (LiPP), lithium 2-(2',2&#x2033;-bipyridine-6&#x2032;-yl)phenolate (LiBPP), 2-(isoquinoline-10-yl)phenolate (LiIQP), and lithium 2-(2-phenylquinazolin-4-yl)phenolate and lithium 2-(4-phenylquinazolin-2-yl)phenolate. In a preferred embodiment, the organo-alkali metal salt is lithium 2-(2&#x2032;,2&#x2033;-bipyridine-6&#x2032;-yl)phenolate (LiBPP). Aspects of the invention also provide films and devices having a film layer prepared from the composition.

Ether dye fixative agents and methods

Provided is a non-cyclopentadienyl-based chromium-ligand complex, preferably a chromium-ligand complex of formula (J): LCr(R)(D)(J), wherein L is a non-Cp monoanionic ligand; Cr (chromium) is in a formal oxidation state of +3 or +2; when Cr formally is Cr, either m is 1 and Ris hydrocarbylene (a hydrocarbylene chromium-ligand complex of formula (J)) or m is 2 and each Rindependently is hydrocarbyl (a dihydrocarbyl chromium-ligand complex of formula (J)), wherein each hydrocarbyl or hydrocarbylene of Rindependently is unsubstituted or substituted by from 1 to 5 R; each Rindependently is a neutral aprotic heteroalkyl, neutral aprotic heterocycloalkyl, neutral aprotic heteroaryl, or neutral aprotic aryl; when Cr formally is Cr, m is 1 and Ris hydrocarbyl (a hydrocarbyl chromium-ligand complex of formula (J)); k is an integer of 0 or 1; D is absent when k is 0 or D is a neutral ligand when k is 1; wherein the chromium-ligand complex of formula (J) is overall neutral and lacks a cyclopentadienyl-based (Cp-based) moiety. Also provided is a chromium catalyst comprising or prepared from the complex. Also provided is a process of making the catalyst and a process employing the chromium catalyst for polymerizing the olefin monomer, especially a straight chain 1-alkene, to prepare the polyolefin, especially a partially chain-straightened poly(1-alkene) or olefin block copolymer. Further provided is the partially chain-straightened poly(1-alkene) or olefin block copolymer prepared thereby. Also provided is a high throughput workflow.
