Abstract: A modified surface with at least one cationic center and at least one compound. The surface can be modified by various methods. The result of these methods is that the cationic center and the compound are connected to the modified surface. The cationic center and the compound are connected to the modified surface so that both of the cationic center and the compound are available upon the modified surface to react with other chemicals or microorganisms that come into contact with or near to the modified surface. The availability of the cationic center and the compound cause the modified surface to have a functionality that it would not otherwise have. The number of molecules of the cationic center relative to the number of molecules of the at least one compound may influence the functionality of the modified surface.

Abstract: An electrode and an organic electroluminescent device using the same are provided.
