Abstract
A new light-emitting poly(p-phenylenevinylene) (PPV) derivative containing trialkoxyalkyl substituents (TAA) as color tunable groups was synthesized through a Gilch polymerization, and the light-emitting properties of the polymer (TAA-PPV) were investigated. The emission of TAA-PPV was found to be highly blue-shifted to the green region, with peak absorption and band edge near 399 and 490Â nm, respectively. The PL emission maximum of TAA-PPV thin films was found to be at approximately 493Â nm. Light-emitting devices were fabricated with the configuration ITO (indium-tin oxide)/PEDOT/polymer/Ca/Al and produced very bright green emission. This device with TAA-PPV as the emissive layer had a maximum brightness of 3600Â cd/m2 and a maximum power efficiency of 0.77Â lm/W.
