ABSTRACT:
Organic devices comprising an organic layer, wherein the organic layer comprises: (a) a host material formed of a covalently cross-linked matrix comprising an organic charge transport material, and (b) a dopant. The charge transport material has reactive groups for forming cross-links. The cross-linked matrix may allow the organic layer to be solvent resistant. The dopant may protect the cross-linked matrix from electrochemical degradation. The dopant may be a charge acceptor and/or capable of forming covalent bonds with free reactive groups on the cross-linked charge transport material.
