title: Synthesis and structure of bull's horn-shaped oligothienoacene with seven fused thiophene rings.
abstract: A novel bull's horn-shaped oligothienoacene with seven fused thiophene rings (1) based on dithieno[2,3-b:2',3'-d]thiophene (2) was efficiently synthesized. X-ray diffraction data indicate that 1 possesses an extraordinary compressed sandwich-herringbone arrangement and shows strong intermolecular S···C and S···S interactions. In addition, the UV/vis properties, theoretical calculations, and cyclic voltammetry behaviors of 1 are also described.
