Cross-linkable copper phthalocyanine complexes

A method of forming an organic layer, comprising:

• providing a solution containing a cross-linkable copper complex that comprises a phthalocyanine core and one or more cross-linkable functionalities linked to the phthalocyanine core;
• depositing the solution on a surface;
• and
• cross-linking the cross-linkable copper complex to form an organic layer on the surface.

An organic electronic device comprising:

• a first electrode;
• a second electrode disposed over the first electrode;
• and
• an organic layer disposed between the first electrode and the second electrode, wherein the organic layer comprises a cross-linked material having a plurality of cross-linked copper phthalocyanine molecular subunits.
