Single crystal n-channel field effect transistors from solution-processed silylethynylated tetraazapentacene

Single crystals of TIPS-TAP were grown from solution using poor solvents. With gluing silver-films as source and drain electrodes, the crystals exhibited field-effect mobility up to 1.77 cm2 V−1s−1, which is one of the highest values reported for solution-processed n-channel single crystal OFETs.
