General description

Electronic structure of the lowest excited triplet state of 6,13-pentacenequinone has been studied by continuous-wave time-resolved electron paramagnetic resonance and pulsed electron nuclear double resonance.

Application

6,13-Pentacenequinone has been used in:
  • deposition of 6,13-pentacenequinone thin films on n-Si substrates by thermal evaporation
  • as precursor to diarylpentacenes, potential organic field-effect transitors
