The copolymer with carbazole and iridium-containing groups in the side chains (P1) and the terpolymer with additional organosilicon units (P2) were synthesized by the ring-opening metathesis polymerization (ROMP). The photoluminescence (PL) and electroluminescence (EL) properties of the synthesized polymeric materials were investigated. The iridium-containing terpolymer exhibited the most efficient EL characteristics: the maximum brightness is 1780 cd m−2 (21 V), the maximum current efficiency is 23.3 cd A−1 (13 V), and the maximum power efficiency is 6.4 lm W−1 (11 V). The color coordinates of the emission in the CIE (Commision Internationale de l’Eclairage) diagram (0.21, 0.71) correspond to the green color and remain virtually unchanged in the whole driving voltage range.
