Abstract
A liquid composition (e.g., inkjet fluid) for forming an organic layer of an organic electronic device (e.g., an OLED). The liquid composition comprises a small molecule organic semiconductor material mixed in an aromatic solvent. The aromatic solvent, when left as a residue in the organic layer, is capable of presenting relatively reduced resistivity to charge transport or facilitating charge transport in the organic layer that is deposited, as compared to other conventional solvents. In certain embodiments, the aromatic solvent compound has the following formula: wherein R represents one or more optional substituents on the benzene ring, wherein each R is independently an aliphatic group containing from 1-15 carbon atoms; and wherein X is a substitution group that contains an electron-withdrawing group selected from nitrile, sulfonyl, or trifluoromethyl.
