A novel alternating TBTBT (“T” - thiophene, “B” - benzothiadiazole) compound has been synthesized from readily available precursors using efficient direct arylation and Stille cross-coupling reactions. Molecular structure of TBTBT has been revealed using single-crystal X-ray diffraction. TBTBT was applied as electron donor material for vacuum-processed small-molecule planar and bulk heterojunction solar cells and ambipolar semiconductor for organic field-effect transistors.
