Abstract
AbstractElectroluminescence (EL) properties of a new poly(aryleneethynylene) and a related copolymer were studied. They are poly[(3,3′‐dimethyl‐1,1′‐biphenyl‐4,4′‐diyl)ethynediyl(2,5‐dioctyl‐1,4‐phenylene)ethynediyl] (PPEBE) and related copolymer (PPEBE‐co‐mP) containing 20 mole % of 1,3‐phenylene units. Both polymers are blue‐light emitters; the former was found to perform better than the latter when the light‐emitting diode (LED) device had the configuration of ITO/PEDOT/polymer/Li:Al. The device constructed with the former polymer exhibited the external quantum efficiency of 0.05 and the maximum brightness higher than 400 cd/m2 with its EL spectrum showing maxima at λ = 445 and 472 nm. The performance of the device constructed with the copolymer was about one fifth of the device fabricated with the homopolymer.
