NOVELTY - Covalently binding an organic metal complex having at least one metal center and at least one organic ligand to a polymer comprises performing a first reaction comprising a first reactant in the form of the organic metal complex and a second reactant in the form of a polymer, where during the reaction, the metal complex is covalently bonded to the polymer, and the reaction is catalyzed by the metal complex.    USE - The polymer having a covalently bound organic metal complex is useful as emitter or absorber in an optoelectronic component comprising organic LED, light-emitting electrochemical cells, organic LED-sensors, preferably non-hermetically outwardly shielded gas and steam sensors, optical temperature sensors, organic solar cells, organic field effect transistors, organic diodes, organic photodiodes or down conversion systems. The organic metal complex is useful for connecting or crosslinking the metal complex with the second reactant to form a multidimensional network (all claimed).    ADVANTAGE - The process produces polymer having a covalently bound organic metal complex in high yield and high selectivity.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a polymer having a covalently bound organic metal complex (Q) obtained by the process;    (2) a process for preparing a layer of a polymer bound organometallic complex comprising applying a reaction product of a first reaction comprising the first reactant in the form of the organic metal complex and the second reactant in the form of the polymer, preferably for forming a multidimensional network on a solid support, and performing a reaction between the first reactant and the second reactant, where the reaction between the first reactant and the second reactant is catalyzed by the metal complex; and    (3) the organic metal complex having the metal and organic ligand, characterized by an anchor group of a first anchor group species for reaction with an anchor group of a second anchor group species for crosslinking, where one of the two anchor groups of the metal complex, during a crosslinking reaction to the anchor group of the second reactant for forming a multidimensional network forms a covalent bond.
