Title:
METAL COMPLEX AND COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2010/117075
Kind Code:
A1
Abstract:
Disclosed is a metal complex comprising a conjugated compound having a molecular weight of 200 or more and a metal nano-structure having an aspect ratio of 1.5 or more, wherein the conjugated compound is adsorbed on the metal nano-structure. For example, the metal complex comprises: a compound having a group represented by formula (I) [wherein Ar1 represents an optionally substituted aromatic group having a valency of (n1+1) ; R1 represents a direct bond or a group having a valency of (m1+1); X1 represents a group containing a hetero atom; and m1 and n1 independently represent an integer of 1 or more, wherein when there are multiple R1's, X1's and m1's, these residues may be the same as or different from one another], a repeating unit represented by formula (II) [wherein Ar2 represents an optionally substituted aromatic group having a valency of (n2+2) ; R2 represents a direct bond or a group having a valency of (m2+1); X2 represents a group containing a hetero atom; and m2 and n2 independently represent an integer of 1 or more, wherein when there are multiple R2's, X2's and m2's, these residues may be the same as or different from one another], or both of the group and the repeating unit; and a metal nano-structure having an aspect ratio of 1.5 or more, wherein the compound is adsorbed on the metal nano-structure. The metal complex is useful in electronic elements such as light-emitting elements, solar batteries, organic transistors and others.
