Various studies have been done using dendrimers as emissive materials for OLEDs, although efficiencies are still significantly lower than those offered by evaporated devices. In this study, dendrimers were synthesized. Photoluminescence (PL) and Electroluminescence (EL) characteristics of Benzoxazole dendrimers were investigated by fabricating the device of structure such as ITO/PVK: Benzoxazole dendrimers: PBD/Li:Al. We used PVK as hole transport material and blended with PBD as electron transport material. The Benzoxazole dendrimers studied here used emissive material. The PL spectra of 1st generation and 2nd generation Benzoxazole dendrimers show blue emission at 438 nm. The EL spectra of 1st generation and 2nd generation Benzoxazole dendrimers were observed at the wavelength of 441 nm and 447 nm.
