General description

Selenophene is a heterocyclic building block. Synthesis of selenophene-based heteroacenes has been reported. Synthesis of selenophene-thiophene block copolymers has been reported. The electron transmission spectra of selenophene has been recorded in the 0-6eV energy range.

Application

Selenophene may be used:
  • as conjugated linker in the synthesis of organic dyes
  • in the synthesis of selenophene-2-carbonitrile
  • in the synthesis of selenophene diketopyrrolopyrrole polymers
  • as building block for the electrically conducting polyalkyl selenophene

Selenophene-thiophene block copolymers were synthesized and studied. The properties of these novel block copolymers are distinct from those of statistical copolymers prepared from the same monomers with a similar composition. Specifically, the block copolymers exhibit broad and red-shifted absorbance features
