Abstract: The present invention is drawn to a layered organic device, and a method of forming the same. The method includes steps of applying a first solvent-containing organic layer to a substrate and removing solvent from the first solvent-containing organic layer to form a first solidified organic layer. Additional steps include applying a second solvent-containing organic layer to the first solidified organic layer and removing solvent from the second solvent-containing organic layer to form a second solidified organic layer. The first solidified organic layer can be crosslinked, which suppresses negative impact to components in the first solidified organic layer when the solvent of the second solvent-containing organic layer is deposited on the first solidified organic layer.
