Abstract

We have fabricated air stable blue emitting organic electroluminescent devices (OLEDs) from a carbazole based emitting molecule, Bis(3-N-ethylcarbazolyl)terephthalidene (BECP). Our devices emit strong blue at 472 nm with a luminance efficiency of nearly 1 lm/W at a voltage and current density of 8V and 5.7 mA/cm², respectively, reaching a maximum brightness of 5000 cd/m² at 270 mA/cm². In order to tune the emission color from blue to green, we used Bis(3-N-ethylcarbazolyl)cyanoterephthalidene (BECCP), a derivative of BECP with an added cyano group side chain, and compared the electroluminescence (EL) of OLEDs prepared by BECCP to that of BECP based OLEDs.
