Abstract:
1. An organic light emitting diode device, comprising: a substrate; an anode; a cathode; a first device layer comprising an amorphous non-polymeric electrically active material sufficiently soluble in an organic solvent to provide a solution suitable for solution processing, with the proviso that the electrically active material does not comprise tris(8-hydroxyquinolato) aluminum (Alq3), and wherein the first device layer is located between the anode and the cathode; and at least one additional electrically active device layer being susceptible to the organic solvent and comprising an amorphous non-polymeric organic matrix and a light emitting material located in the matrix, wherein the at least one additional device layer is located between the first device layer and the substrate.
