Abstract
The synthesis of a new conjugated rigid-rod polyquinoline, ylene)-6,6' -bis(4-(p-tert-butylphenyl)quinoline)), and its incorporation in light -emitting diodes as the emissive layer are reported. These electrolumi nescent devices, containing 1,1-bis(di-4-tolylaminophenyl)cyclohexan ( TAPC) dispersed in polystyrene as the hole-transport layer, emit brigh t yellow light (lambda(max) = 554 nm) with a quantum efficiency of 0.2 6% photons/electron and a luminance of 280 cd/m(2) at a current densit y of 100 mA/cm(2). These results also demonstrate that the new polyqui noline is a good n-type (electron transport) electroluminescent materi al.
