Abstract
The present invention relates to polymeric metal complexes comprising metallic complexes covalently bound to conjugated polymers and luminescent materials containing such polymeric metal complexes. The invention further relates to electronic devices in which the active layer includes such polymeric metal complexes.
Claims41
A polymeric metal complex composition comprising (a) a conjugated polymeric backbone;
- (b) a plurality of a first-type functional groups;
- and (c) a plurality of first-type inert spacer groups, wherein:
- each of the plurality of first-type functional groups is covalently bound to at least one of the plurality of first-type inert spacer groups, which first-type inert spacer groups are covalently bound to the polymeric backbone;
- and
- at least a portion of each of the plurality of first-type functional groups is coordinated to at least one metal.
An luminescent material comprising at least one polymeric metal complex composition comprising (a) a conjugated polymeric backbone;
- (b) a plurality of a first-type functional groups;
- and (c) a plurality of first-type inert spacer groups, wherein:
- each of the plurality of first-type functional groups is covalently bound to at least one of the plurality of first-type inert spacer groups, which first-type inert spacer group is covalently bound to the polymeric backbone, and
- at least a portion of each of the plurality of first-type functional groups are coordinated to at least one metal.
An organic electronic device comprising at least one polymeric metal complex composition comprising (a) a conjugated polymeric backbone;
- (b) a plurality of a first-type functional groups;
- and (c) a plurality of first-type inert spacer groups, wherein:
- each of the plurality of first-type functional groups is covalently bound to at least one of the plurality of first-type inert spacer groups, which first-type inert spacer group is covalently bound to the polymeric backbone, and
- at least a portion of each of the plurality of first-type functional groups is coordinated to at least one metal.
