Abstract
A new n-type conducting polymer poly (p-pyridyl vinylene), (PPyV) was synthesized by the C-C cross coupling reaction of 2, 5-dibromopyridine and 1, 2-bis (tributylstannyl) ethylene catalyzed by palladium complex. We have reported investigations of electroluminescence (EL) in PPyV which we have used in a range of single-and double-layer EL devices. EL in the yellow region of the spectrum with a maximum at 585nm was observed from PPyV sandwiched between indium-tin-oxide and Al electrodes. In double-layer device which incorporate a thin film of poly (p-phenylene vinylene), (PPV) as a hole transport layer, yellow-orange emission with 0.08% external quantum efficiency can be achieved. EL originates from the radiative decay of the chromophore singlet polaron exciton created as a result of the recombination of injected charge carriers.
