Carbazole‐Dendronized Luminescent Radicals

Angewandte Chemie, 2023
AbstractA 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

Photochemical degradation of polyhalogenated carbazoles in hexane by sunlight.

Science of the Total Environment, 2019
Polyhalogenated carbazoles (PHCZs) are a class of halogenated dibenzopyrrole, which have been increasingly detected in the environment and found to be bioaccumulative and potentially toxic. However, their environmental transformation potential is largely

Determination of carbazole and halogenated carbazoles in human serum samples using GC-MS/MS.

Ecotoxicology and Environmental Safety, 2019
Carbazole and halogenated carbazoles have been widely detected throughout the environment in soil, river deposits, and lake sediments. Human exposure to these compounds may occur through inhalation, drinking water, dietary intake and/or skin contact, and

Carbazole Alkaloids III

1991
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 ...

Tuning the Photophysical and Electroluminescence Properties in Asymmetrically Tetrasubstituted Bipolar Carbazoles by Functional Group Disposition.

ACS Applied Materials and Interfaces, 2018
Carbazoles decorated with both donor and acceptor fragments offer a classical way to optimize bipolar functional properties. In this work, a series of carbazoles featuring triphenylamine donors and cyano acceptors are synthesized and their structure ...

Does the length matter? - Synthesis, photophysical, and theoretical study of novel quinolines based on carbazoles with different length of alkyl chain

Dyes and pigments, 2019
Donor-acceptor (D-A) system based on 2,4-dicarbazolyl-substituted quinolines (Q2-Q5) with different length of alkyl chain at carbazole, viz CH3 (Q3), C8H17 (Q4), C10H21 (Q5), and different attachment of carbazole to quinoline core, and in addition a 4 ...

Presence of carbazole and polyhalogenated carbazoles in human urine

Science of The Total Environment
Exposure 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.
