Abstract

The invention relates to the preparation of an organic transition metal complex cross-linked into a multi-dimensional network, comprising the performance of a first reaction, which comprises a first reactant in the form of an organic metal complex and a second reactant for the formation of a multi-dimensional network, where the organic metal complex is cross-linked to form the multi-dimensional-network during the reaction.

First claim

The invention claimed is:

1. A method for cross-linking of an organic transition metal complex into a multi-dimensional network, comprising:
performing a first reaction which comprises:
a first reactant in the form of the organic transition metal complex; and
a second reactant for formation of the multi-dimensional network;

wherein the organic transition metal complex is cross-linked during the first reaction by formation of covalent bonds to form the multi-dimensional network;
wherein the organic transition metal complex comprises at least two anchor groups of a first anchor group species for the covalent bonding of the organic transition metal complex into the multi-dimensional network and the second reactant comprises at least one anchor group of a second anchor group species;
wherein the cross-linking of the organic transition metal complex proceeds by reaction of each of the at least two anchor groups of the organic transition metal complex with an anchor group of the second reactant;
wherein the cross-linking is not a copolymerization, the copolymerization comprising a reaction in which a plurality of different monomers are cross-linked with each other;
wherein the second reactant and the first reactant are different from each other; and
wherein the second reactant is selected from the group consisting of an oligomer and a polymer wherein the first and the second anchor group species are selected from corresponding pairs of:

R 1 -R 6 can each independently be hydrogen, a halogen or substituents, which are bound via —OR*, —NR* 2 or —SiR* 3 as well as alkyl, aryl, heteroaryl, alkenyl, alkynyl groups or substituted alkyl, aryl, heteroaryl and alkenyl groups;
R*=organic group selected from the group consisting of hydrogen, a halogen or deuterium, as well as alkyl, aryl, heteroaryl, alkenyl, alkynyl groups or substituted alkyl, aryl, heteroaryl and alkenyl groups;
Wherein EWG is an electron withdrawing group.

2. The method according to claim 1 , wherein the multi-dimensional network is insoluble in a common organic solvent.

3. The method according to claim 1 , wherein the first reaction further comprises at least one of a third reactant and a fourth reactant.

4. The method according to claim 3 , wherein the third reactant comprises two anchor groups of the second anchor group species, and wherein each of the anchor groups of the third reactant can form a covalent bond with one of the first anchor group.

5. The method according to claim 3 , wherein the fourth reactant comprises an anchor group of the first or second anchor group species, and wherein the fourth reactant is for transport or blocking of electrical charges.

6. The method according to claim 1 , wherein the first reaction takes place in the presence of a catalyst, and wherein the organic transition metal complex comprises the catalyst.

7. The method according to claim 3 , further comprising performing a second reaction for the production of a multi-layer arrangement, the second reaction comprising:
a fifth reactant in form of the organic transition metal complex; and
a sixth reactant for formation of the multi-dimensional network;
wherein the organic transition metal complex is cross-linked by the formation of covalent bonds during the second reaction to form the multi-dimensional network.

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