Application

3-Bromothiophene can be used as a reactant to synthesize:
  • 3,3-Bithiophene via borylation followed by Suzuki coupling.
  • 3-Alkylthiophenes by NiDPPP++ catalyzed cross-coupling with Grignard reagents.
  • 3-Lithiothiophene by treating with n-butyllithium in hexane.
  • Derivatives of thienylenic α, ω−diformyl−α−oligothiophenes.
  • N-(2-(3-bromothiophen-2-yl)phenyl)methanesulfonamides by coupling at the 2-position with N-arylmethanesulfonamides, mediated by iodobenzene diacetate (178721).

We report that nanoparticles prepared from appropriately functionalized polythiophenes once administered to live cells can acquire phototransduction properties under illumination, becoming photoactive sites able to absorb visible light and convert it to an electrical signal through cell membrane polarization.
