Abstract
A method of forming an organic layer by using a liquid composition comprising a small molecule organic semiconductor material mixed in a ketone solvent. The liquid composition is deposited on a surface to form the organic layer. The ketone solvent may be an aromatic ketone solvent, such as a tetralone solvent. The organic semiconductor material may be cross-linkable to provide a cross-linked organic layer. The method can be used to make organic electronic devices, such as organic light emitting devices. In another aspect, the liquid composition comprises a small molecule organic semiconductor material mixed in an aromatic ether solvent. Also, provided are liquid compositions which can be used to make organic layers.
