Claims70
An amorphous transparent, electrically conductive layer comprising at least one compound of the formula 1
- wherein the substituents are each defined as follows:
- M1, M2:
- identical or different metals in the 0 to 4 oxidation states;
- A, E, G:
- identical or different metals or nonmetals,
- X, Y, R1, R2, R3:
- identical or different metals or nonmetals, identical or different, branched or unbranched, saturated or unsaturated, aliphatic or aromatic, heteroaliphatic or heteroaromatic, substituted or unsubstituted organic or organometallic groups, which may also be bonded via heteroatoms or functional groups to M1 and/or M2
- n, m:
- identical or different numbers in the range of 0-4.
An amorphous transparent, electrically conductive layer, obtained by
- A) applying a solution comprising at least one compound of the formula 1 and, optionally, one or more solvents or carriers, from a liquid solution or from the gas phase to a substrate to form a layer
- wherein the substituents are each defined as follows:
- M1, M2:
- identical or different metals in the 0 to 4 oxidation states;
- A, E, G:
- identical or different metals or nonmetals,
- X, Y, R1, R2, R3:
- identical or different metals or nonmetals, identical or different, branched or unbranched, saturated or unsaturated, aliphatic or aromatic, heteroaliphatic or heteroaromatic, substituted or unsubstituted organic or organometallic groups, which may also be bonded via heteroatoms or functional groups to M1 and/or M2,
- n, m:
- identical or different numbers in the range of 0-4,
- B) optionally, removing the solvent by energy input, then
- C) aftertreating the layer by energy input.

- n, m:
- identical or different numbers in the range of 0-4,
- B) optionally, removing one or more of solvents and additives by energy input, then
- C) aftertreating the layer by energy input.
