Abstract: The invention relates to luminescent compounds with semi-conducting properties, as well as their production and their use in organic light-emitting diodes (OLEDs). The compounds are copolymers comprising a metal complex with a central atom from subgroup 8 of the periodic table of elements.

Abstract: The invention relates to substrates which, at least in regions on a surface, are provided with a coating of a metal, a method for producing such substrates and the use thereof. It is thereby the object of the invention to improve the adhesion of a coating of a metal on electrically non-conducting substrates or layers disposed on substrates. However, further properties can also be improved. For this purpose, the substrates are provided on their surface or on an electrically non-conducting layer with an intermediate layer which improves the adhesion, the coating with the metal being formed in turn on said intermediate layer. On the intermediate layer, a further layer comprising a semiconducting material or material mixture is formed at least in regions. The intermediate layer is formed from a metal oxide and/or a sulphide, the metal oxide and/or sulphide for the further layer which comprises a semiconducting material or material mixture having an injection barrier of less than equals 0.6 eV.
