Abstract

The invention relates to a method for covalently bonding an organic metal complex to a polymeric matrix. The method comprises the performance of a first reaction, which comprises a first reactant in the form of an organic metal complex and a second reactant in the form of a polymer, where during the reaction the metal complex is covalently bound to the polymer. According to the invention, the metal complex catalyzes the reaction.

First claim

The invention claimed is:

1. A method for covalently bonding an organic metal complex with at least one metal center and at least one organic ligand to a polymer, comprising:
performing a first reaction, which comprises:
a first reactant in the form of the organic metal complex; and
a second reactant in the form of a polymer;

wherein the organic metal complex is covalently bound to the polymer during the first reaction;
wherein the first reaction is catalyzed by the metal center of the organic metal complex;
wherein the organic metal complex comprises an anchor group of a first anchor group species for covalently bonding the organic metal complex to the polymer;
wherein the second reactant comprises an anchor group of a second anchor group species for covalently bonding the second reactant to the organic metal complex;
wherein the covalent bonding of the organic metal complex to the polymer is achieved through a reaction of the anchor group of the organic metal complex with the anchor group of the second reactant;
wherein the first and the second anchor group species are selected from the corresponding pairs of the following first and second anchor group species:

wherein:
EWG is an electron withdrawing group;
R 1 -R 6 can each independently be hydrogen, a halogen or —OR*, —NR* 2 or —SiR* 3 as well as alkyl, aryl, heteroaryl, alkenyl, alkynyl groups or substituted alkyl, aryl, heteroaryl and alkenyl groups;
R*=an organic group selected from the group consisting of hydrogen, a halogen or deuterium, as well as alkyl, aryl, heteroaryl, alkenyl, and alkynyl groups or substituted alkyl, aryl, heteroaryl and alkenyl groups; and
X=halogen, OSO 2 Me, OSO 2 Tolyl, or OSO 2 CF 3 .

2. The method according to claim 1 , wherein the metal center of the organic metal complex is selected from the group consisting of Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Hg, Sn and Pb.

3. The method according to claim 1 , wherein the polymer is used as an emitter or an absorber in an optoelectronic component.

4. An optoelectronic component, comprising the polymer of claim 1 , wherein the optoelectronic component is selected from the group consisting of an organic light-emitting diodes (OLEDs), a light-emitting electrochemical cell (LEEC or LEC), an OLED-sensor, wherein the OLED sensor is a gas and vapor sensor which is not hermetically screened from the outside, an optical temperature sensor, an organic solar cell (OSC), an organic field-effect transistor, an organic diode, an organic photodiode and a down-conversion element.

5. The method according to claim 1 , wherein R 1 -R 6 optionally lead to annulated ring systems.
