Technical protocol

More information

DPZ as a photoredox catalyst exhibits excellent photoredox activity in various photoredox reactions with the following catalytic features:

  • Purely organic, metal-free orange compound
  • Absorption of the light within a wide range of the spectra
  • Absorption maxima at 450 nm nicely overlaps the emission maxima of commonly used blue LED source of photons
  • Catalytic performance of DPZ is similar/higher compared to commercially available and commonly used organic photoredox catalysts
  • Very low catalyst loadings - 0.01 - 0.5 % (e. g. Ru(bpy)32+ commonly 0.1 - 5 %)
  • Capability to undergo photoinduced electron transfer via both oxidative and reductive quenching cycle
  • No further interaction with the substrate/products of the catalyzed reactions
  • Easy regeneration after reaction cycle
  • Possible application in the photoredox flow reactors
