Application

2,2′-Bithiophene-5-carboxaldehyde may be used in the synthesis of the following:
  • boron dipyrromethene(BODIPY)oligothiophenes via a multi-step reaction process
  • (2,2′-bithiophene-5-carbaldehyde)-4-nitrophenylhydrazone(BT-NPH) via reaction with 4-nitrophenylhydrazine
  • bithiophene fulleropyrrolidine obtained via refluxing with sarcosine and fullerene
  • azomethine phthalic diimides by heating with N,N-bis(4-amino-2,3,5,6-tetramethylphenyl)naphthalene-1,4,5,8-dicarboximide (DANDI)
