Abstract

Self assembled monolayer field effect transistors (SAMFETs) are reported using a phenylene-thiophene containing semiconducting mesogen attached through a trichlorosilane anchoring group. Monolayer films, covalently attached to silicon dioxide substrates, form in less than 10 h from solution, thanks to the accelerated reaction of the trichlorosilane anchor. Devices exhibit mobilities as high as 1.7 × 10−2 cm2 V−1 s−1, currents of up to 15 μA (on/off current ratio of 106) with device yields close to unity over large areas for channel lengths up to 100 μm.
