摘要： The present invention is directed to a process for preparing a hole transport layer in which a hole transport composition comprising a blend of a hole transport material and transition metal oxide or metal sulfide nanoparticles is deposited as a solution onto a substrate, such as an anode, and then is annealed in a subsequent step. It has been discovered that annealing the hole transport layer comprising the blend of an hole transport material and transition metal nanoparticles improves hole mobility of the hole transport layer in comparison to an identical hole transport layer that has not been subjected to an annealing step.

摘要： 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° C. The organo-alkali metal salt may be selected from the group consisting of lithium 2-(2-pyridyl)phenolate (LiPP), lithium 2-(2′,2″-bipyridine-6′-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′,2″-bipyridine-6′-yl)phenolate (LiBPP). Aspects of the invention also provide films and devices having a film layer prepared from the composition.

摘要： Embodiments are directed to compositions comprising at least one polyethylene (PE) having a density ranging from 0.850 g/cc to 0.970 g/cc, and a polymer processing aid (PPA) masterbatch comprising a PPA polymer blend, at least one polymeric carrier, and optionally up to 12 wt. % of one or more inorganic materials. The PPA polymer blend comprises from 40 to 60 wt. % of one or more fluoroelastomers, and from 40 to 60 wt. % of polyethylene glycol. The composition further comprises at least one fragrance oil. The composition is defined by the equation: RED (PE−PPA masterbatch)
