Organic light emitting diodes (OLEDs) have many applications in modern technology. One benefit of an OLED display is its flexibility; meaning these displays can be curved or bent depending on the intended purpose. Additionally OLED displays are compact and do not require a backlight like other displays, resulting in energy efficiency and savings in operation costs. In order to generate a complete color display, red, green, and blue light emitting molecules are required. Red and green light emitting molecules have been successfully synthesized with relatively long lifetimes and stabilities. However, thus far, synthesis of long lasting and stable blue light emitting molecules has proven difficult. A family of novel organic molecules designed to emit blue light are currently being synthesized and characterized for potential applications in OLEDs. The parent molecule consists of three subunits, a terminal dendron, a carbazole center, and a conjugated biphenyl unit. Upon synthesis and characterization of the parent molecule, photo emissive properties and durability under oxidative conditions will be studied. Derivatives will also be synthesized to construct a family of novel molecules and variations in wavelength of emission as well as stability to air and heat degradation will be studied.
