- Iridium-Catalyzed Vinylation of Carbazole Derivatives with Vinyl Acetate
-
We report a practical method for the synthesis of vinylcarbazoles via iridium-catalyzed vinylation of carbazoles with vinyl acetate as the vinyl source. This simple and efficient reaction using an iridium catalyst provides a convenient method for producing monomers for the synthesis of poly(N-vinylcarbazole)s, which are used in electroluminescent devices.

- Synthesis and photophysical properties of two branched carbazole-based polymers
-
Two branched carbazole-based polymers having arylene- and arylenevinylene-type structure respectively, were synthesized by copper- or palladium-catalyzed self-polycondensation of AB2 carbazole monomers. The self-Ullmann C-N polycondensation of 3,6-diiodocarbazole led to a branched polymer containing about 15 trisubstituted carbazole (at 3,6 and N-positions) nuclei included in the polymer chain. The self-Heck polycondensation of 3,6-diiodo- or 3,6-dibromo-N-vinylcarbazole led to a branched polyarylenevinylene with trisubstituted carbazole nuclei at 3,6 and N-positions. Both polymers were amorphous materials and soluble in organic solvents and their optical and electrochemical properties were comparable with those of similar polymers with linear structure.
