Application

HAT-CN can be used in studies such as organic electronics, as a charge-transport material, electron-transport material, or active layer component. Its high electron affinity and π-conjugated structure suggest potential use in organic field-effect transistors (OFETs), organic photovoltaics (OPVs), and organic light-emitting diodes (OLEDs). HAT-CN may be studied for potential applications in energy storage, such as batteries and supercapacitors.
HAT-CN is a popular solution-processable hole transport material (HTM) for:

  • Diodes ;
  • Environmentally-friendly organic solar cells (OPVs);
  • Organic phototransistors.
