Polypyromellitimides based on carbazole and substituted carbazoles
European Polymer Journal, 1982Abstract Polypyromellitimides have been synthesized from carbazole and N -benzylcarbazole by a two-step procedure involving ring-opening polyaddition with pyromellitic dianhydride and subsequent thermal cyclodehydration. The physicochemical, thermal and dielectric properties of the polymers have been studied. The various N -substituents, such as N

Carbazole‐Dendronized Luminescent Radicals
Angewandte Chemie, 2023AbstractA series of carbazole‐dendronized tris(2,4,6‐trichlorophenyl)methyl (TTM) radicals have been synthesized. The photophysical properties of dendronized radicals up to the fourth generation were compared systematically to understand how structure–property relationships evolve with generation. The photoluminescence quantum yield (PLQY) was found to

The European dye stuff industry originally provided the main stimulus for development of the chemistry of carbazoles since the discovery of the first member of the group, carbazole (1) from coal tar in 1872 by Graebe and Glazer (35). The isolation of carbazole as a degradation product of strychnine (2) by Clemo and Perkin (18) in 1924 provided further ...

Presence of carbazole and polyhalogenated carbazoles in human urine
Science of The Total EnvironmentExposure to carbazole (CZ) and polyhalogenated carbazoles (PHCZs) may pose a threat to human health, owing to their potential dioxin-like toxicity. Until now, the presence of these chemicals in the human urine from the general population is still unclear.

Copper(II)-Catalyzed Iodinations of Carbazoles: Access to Functionalized Carbazoles
The Journal of Organic Chemistry, 2019A copper-catalyzed iodination of carbazoles has been developed. Barluenga's reagent IPy2BF4 is used to generate a soft electrophilic halonium species for the iodination of the carbazoles. This report represents the first concept of copper-catalyst-promoted electrophilic halogenation of carbazoles.
