Abstract
An electroluminescent device (20) having a first layer comprising a fluorinated first organic compound with one or more fluorene residues and soluble in a fluorinated solvent, the first layer being adjacent to a second layer having second organic compound that is insoluble in a fluorinated solvent, and methods and materials for making said device.
Claims23
A method of forming an organic electronic device comprising a first layer comprising a fluorinated first organic compound having one or more fluorene residues, the first layer adjacent a second layer comprising a fluorine-free second organic compound, the method comprising:
- depositing a second solution comprising a second solvent to form the second layer;
- and
- depositing a first solution comprising the fluorinated first organic compound and a first fluorinated solvent on the second layer to form the first layer,
- wherein the second organic compound is insoluble in the first fluorinated solvent, wherein the second organic compound is a conductive or semiconductive compound, and wherein the second solvent is an organic solvent.
