Abstract
We synthesized Bis(3-N-ethylcarbazolyl) terephthalidene(BECP) and Bis(3-7-ethyl-carbazolyl) cyanoterephthalidene(BECCP) and characterized EL properties of these materials. Our device shows a strong blue emission at 472 nm with a luminance efficiency of 0.9 lm/W at a voltage, a current density, and a brightness of 8 V, 5.7 mA/cm
