    摘要: 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.
