We report on the preparation of large area coverage of well-oriented films of dithiophene-tetrathiafulvalene (DT-TTF) from solution by using the zone casting technique. The X-ray analysis shows that the molecules are highly ordered in the films with the stacking direction parallel to the substrate. We further demonstrate that it is possible to prepare organic field-effect transistors (OFETs) employing these films. The devices reveal a remarkable OFET mobility with a maximum value of 0.17 cm(2)/V s. The fact that the films are prepared from solution makes these devices eminently suitable for low-cost electronics. (c) 2007 Elsevier B.V. All rights reserved.
