Abstract
A method of patterning an organic device includes depositing a first organic functional layer over a device substrate to form a first intermediate structure, the first organic functional layer having a first function such as hole transport or electron transport. The first intermediate structure is coated with a fluoropolymer and treated in a processing agent comprising a fluorinated solvent in which the fluoropolymer is soluble to form a processed intermediate structure. A second organic functional layer is deposited over at least a portion of the first organic functional layer, the second organic functional layer also having the first function.
