The title compound, C(21)H(18)N(2), was obtained as the product of the reaction between 9-ethyl-9H-carbazole-3-carbaldehyde and aniline in ethanol. The crystal packing is stabilized mainly by C-H⋯π inter-actions between the carbazole benzene rings and the methyl-ene H atoms.

The title compound, C(19)H(13)BrClN, was synthesized by N-alkyl-ation of 4-chloro-1-(chloro-meth-yl)benzene with 3-bromo-9H-carbazole. The carbazole ring system is essentially planar, with a mean deviation of 0.028 Å, and it makes a dihedral angle of 91.2 (3) Å with the plane of the benzene ring.

Carbazole is one of the typical heterocyclic aromatic compounds (NSO-HETs) observed in polluted urban atmosphere, which has become a serious environmental concern. The most important atmospheric loss process carbazole reaction with OH radical. present work investigated mechanism OH-initiated oxidation degradation by using density functional theory (DFT) calculations at M06-2X/6-311++G(3df,2p)//...

The title compound, C(19)H(12)Br(3)N, was synthesized by N-alkyl-ation of 1-bromo-4-(bromo-meth-yl)benzene with 3,6-dibromo-9H-carbazole. There are two unique mol-ecules in the asymmetric unit. The carbazole ring system is essentially planar, with a mean deviation of 0.0402 Å for one mol-ecule and 0.0279 Å for the other. The carbazole planes are inclined to the benzene ring planes at dihedral a...

Excited state proton transfer of carbazole gives rise to dual fluorescence from the two prototropic species. Simultaneous consideration of the two emissions takes care of many of the instrumental artifacts. The relative intensity of the two emissions of carbazole is sensitive not only to the pH of the bulk medium but also the microenvironment around the probe. Hence, excited state proton transf...

THE TITLE COMPOUND KNOWN AS GLYCOZOLIDAL (SYSTEMATIC NAME: 2,7-dimeth-oxy-9H-carbazole-3-carbaldehyde), C(15)H(13)NO(3), is a naturally occurring carbazole, which was isolated from the roots of Clausena lansium. The carbazole ring system is essentially planar, with an r.m.s. deviation of 0.0093 (1) Å. In the crystal, inter-molecular N-H⋯O hydrogen bonds connect the mol-ecules into a chain along...

We report a label-free fluorescent strategy to study the distribution and stability of DNA origami nanostructures in live, cellular systems, using carbazole-based biscyanine as a probe molecule which has the characteristic property of restriction of intramolecular rotation (RIR) induced emission.

Incorrect crystal data was deposited with the CCDC along with the original article. This led to further errors in the ESI, specifically in Fig. S10 and Fig. S11 as well as Tables S4, S7 and S13. Correct crystal data has been deposited with the CCDC to replace the original data and both the ESI and the crystal data for this article available online have since been replaced with corrected version...

A rapid and efficient route has been developed for the synthesis of 9-methoxycarbonylindolo[3,2-a]carbazole derivatives. The key steps in this approach involved an aromatic amination and an oxidative biaryl coupling. Via the present route, indolo[3,2-a]carbazole derivatives are available in 3-4 steps based on commercially available starting materials.
