This invention provides phenylene-thiophene compounds that exhibit useful electronic properties such as high mobility and high on/off ratio. The invention also provides electronic devices incorporating these compounds. These devices include field effect transistors (FETs), thin film transistors (TFTs), display devices, light-emitting diodes, photovoltaic cells, photo-detectors, and memory cells. Further, the invention also describes a method for manufacturing these field effect transistors. The invention describes an electronic device comprising one or more compounds represented by Formula: (I) where R is selected from substituents comprising 1-20 carbon atoms, wherein the substituents are selected from substituted or unsubstituted alkyl groups, substituted or unsubstituted alkenyl groups, and substituted or unsubstituted alkynyl groups; n is an integer selected from 2 through 6; and m and m′ are integers selected independently from 1 through 3.
