A novel norbornene-dicarboximide monomer functionalized with carbazole was synthesized and effectively polymerized using the Grubbs 3rd generation initiator. Extensive characterization through NMR, GPC, FT-IR, DSC, and UV-vis spectroscopy confirmed the polymer's characteristics. The polymer demonstrated the anticipated nearly 1:1 vinylene cis-trans microstructure, possessing a molecular weight of 26800 g/mol and a polydispersity index of 1.11. Its glass transition temperature, as determined by DSC, was 117 °C. UV-vis analysis confirmed the presence of the polymer-bound carbazole group, evidenced by a λmax of 220 nm, compared to 222 nm for carbazole and 221 nm for the monomer.
