  • Electron transport layer and film having improved thermal stability
    Patent number: 9972792
    Abstract: 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.

  • METHOD OF PREPARING A HOLE TRANSPORT LAYER HAVING IMPROVED HOLE MOBILITY
    Publication number: 20170054100
    Abstract: 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.
