Synthesis and Molecular Properties of Partially Fluorinated DNTTs**

1,2,3,4-Tetrafluoro-dinaphthothienothiophene (F4DNTT) and 1,2,3,4,8,9,10,11-octafluoro-dinaphthothienothiophene (F8DNTT) were synthesized via bisthiomethyl alkene intermediates which were accessible by McMurry coupling or Wittig olefination of partially fluorinated naphthalene precursors. DFT-based electronic structure calculations, near-edge X-ray absorption fine structure (NEXAFS) spectroscopy, and UV/Vis measurements were used for HOMO/LUMO gap determination and to analyze the electronic structures of the partially fluorinated DNTTs. Reduced exciton binding was observed in thin films.

Rh(ii)/phosphine-cocatalyzed synthesis of dithioketal derivatives from diazo compounds through simultaneous construction of two different C-S bonds

Rhodium(ii)/phosphine-cocatalyzed bis-sulfuration of α-diazocarbonyl compounds using thiosulfonates as the sulfenylating agent, which provided two sulfur-containing moieties, was developed via simultaneous inter- and intra-molecular C-S bond formation. This novel protocol provides a rapid synthetic route to dithioketal derivatives in moderate to good yields in an atom-economic process. The transformation is proposed to proceed through phosphine ylide formation followed by S(O2)-S bond cleavage and rearrangement.
