Abstract
A cyclometallated platinum(II) complex with 2-(2,4-difluorophenyl)pyridinyl and norbornene-substituted pyrazolonate ligands (1) was synthesized. Based on monomer 1, the copolymers with carbazole and platinum-containing fragments in the side chains (P1, P2) and terpolymers with additional organosilicon units (P3, P4) were obtained by ring-opening metathesis polymerization (ROMP). Photoluminescent and electroluminescent properties of the synthesized polymers were investigated. Copolymer P1 exhibited green electroluminescence, and polymeric emitters P2—P4 generated white irradiation. The maximum current efficiency (15.69 cd A–1) and maximum power efficiency (2.17 lm W–1) were reached for emitter P3.
