Organic field effect transistor based on a novel soluble pentacene precursor and operating at low voltages

We report the characterization of organic field effect transistors fabricated with a novel soluble pentacene precursor. The detail to obtain this novel precursor and the chemical characterization of this precursor are given. The soluble precursor has been deposited on a thin oxide film with lithographically defined electrodes. The determined carrier mobility in organic film is of order of 0.01-0.05 cm2 V−1 s−1.
