Synthesis and Study of Carbazole Derivatives for Potential Application in Organic Light Emitting Diodes (OLEDs)

Abstract

Organic Light-Emitting Diodes (OLEDs) are an area of interest due to their advantages in technological applications. OLEDs are devices that use thin films of organic materials to produce light emissions. Various power sources can operate OLED displays, including electrical, solar, and battery.1 A complete color display requires red, green, and blue light emitters. Currently, stable molecules that emit red and green light have been successfully synthesized. Stable blue light emitting molecules have been more challenging to synthesize and commonly experience short lifetimes and degradation from heat and oxygen exposure. The focus of this research is to create a family of stable carbazole-based derivatives with the ability to emit blue light. The parent molecule is comprised of a carbazole center that is linked to two terminal subunits, diphenylacetylene and 1-(2’, 3’, 4’, 5’-Tetratphenyl)phenyl-4-bromo-benzene. Currently, the research is focused on coupling the carbazole moiety with the borylated diphenylacetylene through a Suzuki-Miyaura coupling reaction and purifying the resulting product.
