Abstract: A liquid composition (e.g., inkjet fluid) for forming an organic layer of an organic electronic device (e.g., an OLED). The liquid composition comprises a small molecule organic semiconductor material mixed in a solvent in which the solvent compound has the following formula: wherein R1 is C1-6 alkyl; R2 is C1-6 alkyl; and R3 is one or more optional substitutions independently selected from C1-6 alkyl and lower aryl.

Abstract: A method of fabricating an organic light emitting device is provided. A first electrode is provided, over which the rest of the device will be fabricated. A first organic layer is deposited over the first electrode via solution processing. The first organic layer includes: i. an organic host material of the first organic layer; ii. a first organic emitting material of the first organic layer; iii. a second organic emitting material of the first organic layer; A second organic layer is deposited over and in direct contact with the first organic layer. The second organic layer includes an organic emitting material of the second organic layer. A second electrode is then deposited over the second organic layer. The device may include other layers.
