Recent Advances in the Chemistry of 9H-Carbazoles

Polychalcones Based on Carbazole-derived Building Blocks: Synthesis by Acetylative Polycondensation

“…The FriedelÈCrafts acylation of N-alkylated carbazoles is known to occur readily. 35 When adding the starting alkylcarbazoles to an acylating complex, 3,6-diacylated derivatives were reported to be formed even at a molar carbazole/acyl halide ratio less than equimolar.40 Indeed, having attempted the preparation of 3-acetyl-9-dodecylcarbazole (6) according to this route, we have isolated 3,6-diacetyl-9-dodecylcarbazole (7) in 89% yield as calculated from the amount of acetyl chloride, which was equimolar to that of the starting 9-dodecylcarbazole (4). The monoacetylated derivative 6 was synthesized in a reverse way by adding acetyl chloride to a mixture of 4 and AlCl 3 .…”

Synthesis and Photophysical Properties of Pyrene-Based Multiply Conjugated Shaped Light-Emitting Architectures: Toward Efficient Organic-Light-Emitting Diodes

“…It is well demonstrated that the thermal stability or glass-state durability of organic compounds could be greatly improved upon incorporation of a carbazole or fused aromatic moiety in the core structure (Kuwabara et al, 1994;Koene et al, 1998;O'Brien et al, 1998). Furthermore, the carbazole moiety can be easily functionalized at its 3-, 6-, or 9-positions and covalently linked to other molecular moieties (Joule, 1984), such as alkyl, phenyl, diarylamine, pyrenyl, etc. Similarly, the fluorene molecule can also be easily functionalized at its 2-, 7-, and 9-positions (Lee et al, 2001;Zhao et al, 2006).…”

New method of synthesis of oligoetherols with carbazole ring

“…It is weakly acidic due to the presence of nitrogen-attached hydrogen. 1 Carbazole and its derivatives are used in chemistry and technology of polymers, dyes, herbicides, surfactants, and other polymer additives. [2][3][4][5][6][7][8] Some derivatives of carbazole reveal unique physical properties like photo-and electroluminescence, liquid crystallinity, electric conductance, and nonlinear optical properties.…”
