The invention provides methods for the application of active materials onto active surfaces useful in organic electronic devices. The methods of the invention include selecting a liquid composition including an active material and a suitable liquid medium whereby when the liquid composition is deposited on the desired active surface it has no greater than about a 40° contact angle; treating the active surface to raise its surface tension before the deposition of a liquid composition containing the desired active material is deposited thereon; and combination thereof. The invention also provides organic electronic devices having at least two active layers, wherein at least one active layer comprises an active material that was deposited using at least one practice of the method of the invention.
本发明提供了将活性材料应用于有机电子设备中的活性表面的方法。本发明的方法包括选择一种包括活性材料和适当液体介质的液体组合物,当该液体组合物沉积在所需的活性表面上时,其接触角不大于约 40°;在沉积含有所需活性材料的液体组合物之前,处理活性表面以提高其表面张力;及其组合。本发明还提供了具有至少两个活性层的有机电子器件,其中至少一个活性层包括使用本发明方法的至少一种做法沉积的活性材料。
