THE TITLE COMPOUND [SYSTEMATIC NAME: 1-meth-oxy-2-(3-methyl-but-2-en-yl)-9H-carbazole-3-carbaldehyde], C(19)H(19)NO(2), is a natural carbazole which was isolated from the twigs of Clausena lansium. The carbazole ring system is essentially planar with a mean deviation of 0.0068 (10) Å. The aldehyde substituent is approximately co-planar with the attached benzene ring with a torsion angle of -8.5...

A series of novel functional carbazole (Cbz)-based carboxylated monomers were synthesized and characterized. A Clauson-Kaas procedure, a deprotection step, amide coupling, and hydrolysis were utilized as key chemical reactions towards the multistep synthesis of monomers in good to excellent isolated yields. The design strategy was further extended to complex carbazole-COOH monomers incorporated...

New organic dyes comprising carbazole, iminodibenzyl, or phenothiazine moieties, respectively, as the electron donors, and cyanoacetic acid or acrylic acid moieties as the electron acceptors/anchoring groups were synthesized and characterized. The influence of heteroatoms on carbazole, iminodibenzyl and phenothiazine donors, and cyano-substitution on the acid acceptor is evidenced by spectral, ...

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.

The title compound, C(19)H(12)Br(2)ClN, was synthesized by N-alkyl-ation of 1-chloro-4-(chloro-meth-yl)benzene with 3,6-dibromo-9H-carbazole. The carbazole ring system is essentially planar (mean deviation of 0.028 Å) and makes a dihedral angle of 74.6 (3)° 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...
