  Facile Synthesis, Structure, and Properties of Benzo[1,2-b:4,5-b‘]dichalcogenophenes

  摘要：

  A general and convenient synthesis of benzo[1,2-b:4,5-b']-dichalcogenophenes including the thiophene (BDT, 1), selenophene (BDS, 2), and tellurophene (BDTe, 3) homologues is developed. Thus synthesized heterocycles are structurally characterized by single-crystal X-ray analysis, and all three homologues are isostructural with one another. They all have completely planar molecular structures packed in a herringbone arrangement. Their physicochemical properties were also elucidated by means of cyclic voltammetry (CV) and LTV-vis spectra.
