Abstract

An organic electronic device consists of one or more electro-active organic or polymer materials sandwiched between electrodes. Critical in such devices is the interface between the electrode and the polymer, where degradation or chemical reaction products may develop that are deleterious to the proper functioning of the device. This is solved by introducing a functional interlayer composed of one or more materials consisting of a molecular backbone bearing phosphonate or phosphate functions, either directly attached or through side chains, said functional layer being disposed between at least one of the respective electrodes and said one or more electro-active materials in the device.
