Abstract :
Structure property relationships have been studied for polar and non-polar electro-luminescent molecules. The polar chromophore with a large red-shift shows a lower turn-on voltage than its non-polar counterparts. The I-V curves show characteristic diode behavior. The external quantum efficiency measurements for the polar molecule shows a four times higher quantum efficiency than the other molecules.
