Organic Electronic and Photonic Compounds

New chemical structures capable of emitting saturated blue light can be easily synthesized. These compounds hold promising emissive properties, especially of blue light, in both a solid state as well as in solution. Potential applications include organic light emitting diodes (OLEDs), organic photovoltaic (OPV) devices, and/or organic field effect transistors (OFETs).  In addition, the light emitting compounds show excellent thermal, oxidative, and photochemical robustness.

Chromophore Synthesis

Even though both fluorescent and phosphorescent organic chromophores have been demonstrated, only fluorescent chromophores are currently on the market. While both lack stability to some degree, fluorescent chromophores suffer from lower efficiency while phosphorescent chromophores lack color purity. The reaction used to produce these new compounds allow much easier synthesis—and of far more structurally complex benzynes—than classical aryne chemistries. Furthermore, the compounds may have higher inherent stability due to their lack of heteroatoms.


  • OLEDs capable of emitting saturated blue light

  • Blue light emissions from both solution and solid state
  • Higher inherent stability from lack of heteroatoms
  • Soluble; printable LEDs could fill a need for flexible LEDs


  • Digital displays for electronics: televisions, cellular phones, computers, large screen HDTVs, etc.
  • Blue lasers
  • White LEDs (i.e., for home lighting)
  • Organic electronic devices and/or organic photonic devices
  • Organic light-emitting diodes (OLEDs), organic photovoltaic (OPV) devices, organic field-effect transistors (OFETs)
