Abstract
A new electroluminescent polyester based on an electrochemically stabl e polypyridylruthenium-(II) complex was prepared by the step-growth po lymerization method. The versatility of changing its solubility by cha nging counteranions makes it possible to prepare thin-film devices by either spin-coating or the self-assembly technique. Single-layer LEDs fabricated from this polymer by the spin-coating method showed bright orange-red emission with a maximum luminance level of 300 cd/m(2). Sel f-assembled multilayers of this material exhibit external quantum effi ciencies close to 1%.
