Novel chemical structures capable of emitting saturated blue light have been easily synthesized. These compounds have potential applications in organic light emitting diodes (OLEDs), organic photovoltaic (OPV) devices, and organic field effect transistors (OFETs).

Organic electronic and photonic materials are used in many electronic devices and displays, and blue organic light emitting devices (OLEDs) specifically are of substantial commercial interest. 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. There remains a need for blue-emitting compounds with improved properties.  Novel chemical structures capable of emitting saturated blue light have been synthesized. These compounds have promising emissive properties, especially because they emit blue light, in both solid-state and in solution. They show excellent thermal, oxidative, and photochemical robustness. The reaction used to produce these new compounds boasts several benefits over classical chemistries: it allows much easier synthesis, produces more complex structures that may have higher inherent stability.  Potential applications include organic light emitting diodes (OLEDs), organic photovoltaic (OPV) devices, and organic field effect transistors (OFETs).    BENEFITS AND FEATURES:  OLEDs capable of emitting saturated blue light Easier to synthesize than competitive routes Blue light emissions from both solution and solid-state Higher inherent stability than other chromophores
