A semi-fluoroalkyl group substituted organic semiconductor polymer and an organic thin film transistor including the same are disclosed. A structure in which hydrogen of only a terminal of an alkyl group is substituted with fluorine exhibits significantly increased hole mobility, and significantly improved properties in terms of thermal stability and chemical stability, as compared to a structure in which all hydrogens coupled to a thiophene ring are substituted with fluorine, or a structure in which hydrogen of the terminal thereof is not substituted with fluorine and only hydrogens of the remaining portion are coupled to the thiophene ring.

A Novel Thermally Reversible Soluble-Insoluble Conjugated Polymer with Semi-Fluorinated Alkyl Chains: Enhanced Transistor Performance by Fluorophobic Self-Organization and Orthogonal Hydrophobic Patterning
self‐assembly via a fluorophobic effect in a non‐fluorous solvent, which leads to an enhanced electrical performance. Ambipolar transistors and inverters with p‐ and n‐ type bilayers are enabled by the unique thermallyreversible soluble‐insoluble properties of SFA‐PQT. More importantly, the hydrophobicity of SFA‐PQT facilitates orthogonalhydrophobicpatterning and a patterned inverter exhibits low
