Abstract
- Abstract: A carbazole compound was synthesized by Knovenagel condensation and characterized by the measurements of 1H NMR, IR and melting point. A multilayer organic light-emitting diode (OLED) using this compound as an active layer was fabricated by vacuum-deposition. This OLED showed a turn-on voltage of approximately 4.5V and a maximum luminance of 910cd/m2. Additionally, the maximum luminous efficiency was found as 0.95cd/A, at this point the device luminance was measured as 146cd/m2 at an operating voltage of 7V. The coordinate value of CIE 1931 was calculated as (x, y)=(0.3843, 0.5345) from the electroluminescence (EL) spectrum, which suggested that the device can emit a yellow-green light.
