    • The present invention relates to an electroluminescent device, which is characterized in that it uses polymer made of ionomer containing metal ions as a charge transport layer. The ionomer contains an ionized metallic salt and the polymer forms a physical cross-linking around the metal. Thus, it has not only a good mechanical property but also a superior thermal stability. Also it shows an ion conductivity due to movement of ion under electric field, and the conductivity can be controlled by varying the concentration of the substituted ion. The ionomer layer can be easily obtained by spin coating method. In addition, the light-emittive quantum efficiency can be greatly increased by inserting the ionomer layer between the electrode and the light-emitting layer to form a stabilized interface. On the other hand, it can be applied to manufacturing of the flexible electroluminescent device because the ionomer is also a polymer.
    • 电致发光器件本发明涉及一种电致发光器件,其特征在于它使用含有离子交联聚合物的聚合物作为电荷传输层。 离聚物包含电离金属盐,聚合物在金属周围形成物理交联。 因此,不仅具有良好的机械性能,而且具有优异的热稳定性。 而且,由于离子在电场下的运动,其表现出离子传导性,并且可以通过改变取代离子的浓度来控制电导率。 离聚物层可以通过旋涂法容易地获得。 另外,通过将离聚物层插入在电极和发光层之间以形成稳定的界面,可以大大提高发光量子效率。 另一方面,它可以应用于柔性电致发光器件的制造,因为离聚物也是聚合物。
