TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The electrode is an anode, and the first organic layer is deposited in contact with the anode. The first organic layer is a hole injection layer. The second organic layer is a hole transporting layer (125), a hole blocking layer, an electron transporting layer, an electron injection layer, or an emissive layer.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: In the method, a second organic layer containing a nonpolar solvent is deposited over the first organic layer, and the first organic layer is insoluble to the non-polar solvent in the second organic layer. The solution process is spin coating or inkjet printing. The organic electron acceptor and the organic electron donor are mixed at a mole ratio of 1:1 or 2:1. The insoluble organic layer forms when the composition is heated at a temperature no less than 100-250 degrees C. The organic electron acceptor and the organic electron donor form a layer that is insoluble in a non-polar solvent. Preferred Components: The non-polar solvent comprises benzene, carbon tetrachloride, cyclohexane, 1,2-dichloroethane, dichloromethane, diethyl ether, heptane, hexane, methyl-tert-butyl ether, pentane, di-iso-propyl ether, toluene (preferred), and xylene.
