Abstract :
Blue fluorescent 3,6-p-acetophenyl N-hexylcarbazole (ANHC) with HOMO level of -5.6 eV comparable to TPD (-5.4 eV) was synthesized. Carrier injection was found to be more efficient in OLEDs using an blend of TPD and ANHC compared to ANHC alone. The electroluminescence is red shifted in comparison to the photoluminescence of either TPD or ANHC.
