Abstract

We present the synthesis, characterization, and transistor performance of a series of semiconductor materials based on dimers of dithienothiophenes with different linkages. The relationship between molecular structure, molecular packing arrangement, film morphology, and device performance has been investigated. Subtle changes in molecular structure lead to dramatically different packing modes in the solid state and greatly affect the transport properties of the carriers. The FET devices based on the vinylene-bridged dimers 4 and 5 show mobilities up to 0.08 cm2V−1 s−1 and 0.89 cm2V−1 s−1 respectively.
