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>I-V</i> 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.
