Efficient Electroluminescence from a New Conjugated Rigid-Rod Polyquinoline

Abstract

A new conjugated rigid-rod polyquinoline, poly (2,2'-p-phenylene)-6,6'-bis(4-(p-tert-butylphenyl)quinoline)), was synthesized and its thin film was used as the emissive layer in light-emitting diodes. The electroluminescent devices, also containing 1,1-bis(di-4-tolylaminophenyl)cyclohexane dispersed in polystyrene as the hole-transport layer, emitted bright yellow light (lambda(max)=554 nm) with a quantum efficiency of 0.16% photons/electron, and a luminance of 200 cd/m2 at a current density of 120 mA/sq cm. These results demonstrate that the new polyquinoline is a good n-type (electron transport) electroluminescent material.
