Abstract
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.
