General description

Naphtho[2,3-a]pyrene (NP) is a polycyclic aromatic hydrocarbon. Its characterization in a bioassay analysis by employing Salmonella typhimurium strain YG1025 by HPLC has been proposed. It is widely employed material for organic electronic devices. Photolysis of naphtho[2,3-a]pyrene radical cations on irradiation with broadband ultraviolet/visible radiation have been investigated by Fourier transform ion cyclotron resonance mass spectroscopy.

Application

Naphtho[2,3-a]pyrene may be used in the following studies:
  • As test compound for the simultaneous mass spectrometric analysis of nonpolar and polar analytes by heat-assisted laser ablation electrospray ionization (HA-LAESI) method.
  • As donor material in the fabrication of organic solar cells (OSCs).
  • As blue and green emitting material in the fabrication of organic light-emitting diodes (OLEDs).
  • As charge transport channel in the fabrication of organic thin-film transistors (OTFTs).
