Electroluminescent Iridium-Containing Functionalized Polynorbornenes Emitting Red Light

Resumo

A new iridium(III) cyclometalated complex NBEpzIr(Tiq)₂ {NBEpzH is 4-[(bicyclo[2.2.1]hept-5- en-2-yl)hydroxymethylidene]-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazole-3-on and TiqH is 1-(thien-2-yl)isoquinoline} was synthesized. Copolymers with carbazole and iridium-containing fragments in side chains were obtained on the basis of the synthesized monomer by the method of ring-opening metathesis polymerization. The copolymers exhibit intense photoluminescence and electroluminescence of deep red color.
