  We developed an efficient and direct method for synthesis of benzothiophene oxides from 1-bromo-2-[2-(trimethylsilyl)ethynyl]benzenes and thionyl chloride as an easily accessible source of the sulfinyl group. Benzothiophenes were also synthesized selectively by simply increasing the amount of thionyl chloride. These methods achieved efficient syntheses of various benzothiophene oxides and benzothiophenes

  Spirobifluorene based non-fullerene acceptors (NFAs) having meta-ethylhexyl oxy (m-OEh) substituents (PBDB-T: spiro-bridged NFAs) were synthesized. The orthogonal molecular structure of the m-OEh-substituted spirobifluorene with different end groups provided high solubility and kept the stable morphology between donor-acceptor. Organic Photovoltaic (OPV) device performance was not significantly affected by switching the processing solvent from a chlorinated solvent to an environmentally benign solvent, because suitable morphology and crystallinity were retained. The ITO/ZnO/PBDB-T:spiro-bridged NFA/MoOx/Ag OPV devices prepared using a chlorobenzene as the processing solvent displayed maximum efficiency in the range of 6.44-5.78%, while the devices made using xylene as the processing solvent had a lower maximum efficiency ranging from 6.14-4.66%. The OPV performance of the devices made using chlorobenzene decreased in the order of sp-mOEh-ITIC > spmOEh-ITIC-M > sp-mOEh-ITIC-F > sp-mOEh-ITIC-Cl because an electron donating end group increased open-circuit voltage (Voc), while the electron withdrawing end group increased the short-circuit current density (Jsc). Although the OPV performance of the four spiro-bridged derivatives by xylene was showed to be similar order of that by chlorobenzene solvent processing, the efficiency drop from chlorobenzene solvent to xylene solvent showed following order sp-mOEh-ITIC < sp-mOEh-ITIC-M < sp-mOEh-ITIC-F < sp-mOEh-ITIC-Cl, which depended on the polarity effect of end groups.
