A non-chlorinated mixed solvent system, composed by tetrahydronaphthalene and p-xylene, is demonstrated for high mobility thin film transistors. By optimizing the ratio of the two solvents, charge transport characteristics are significantly improved for polymer devices deposited by spin coating and solution shearing. The non-chlorinated mixed solvents provide a practical and environmentally-friendly approach to achieve high performance polymer transistor devices.
