In the title compound, C(22)H(15)N(3)O(6), the central benzene ring and one of the phenyl rings are essentially parallel to each other, making a dihedral angle of 1.35 (16)°. The dihedral angle between the two phenyl rings is 83.56 (19)°. Intra-molecular C-H⋯N and C-H⋯O hydrogen bonds occur. In the crystal, mol-ecules are linked through C-H⋯O hydrogen bonds. Furthermore, offset face-to-face π-π...

A novel boron-containing π-conjugated compound has been synthesized by the introduction of electron-acceptors (dimesitylboron groups) at the 3,3'-positions of a carbazole dimer (electron-donor). The compound possesses excellent electrochemical properties and high fluorescence quantum yields. In addition, is a sensitive fluorescence sensor with remarkable colour changes and the results could ...

Lithium, used in conjunction with triphenylphosphine or sodium metal, produces a high yield of carbazole when reacted with phenothiazine.

The title compound, C29H24N2OS, contains a pheno-thia-zine moiety linked to a planar carbazole unit (r.m.s. deviation = 0.029 Å) by a C-C single bond. The pheno-thia-zine moiety possesses a typical non-planar butterfly structure with a fold angle of 27.36 (9)° between the two benzene rings. The dihedral angle between the mean planes of the carbazole and pheno-thia-zine units is 27.28 (5)°. In t...

Synthesis and characterization of new carbazolyl derivatives with a pendant stable radical of the TTM (tris-2,4,6-trichlorophenylmethyl radical) series are reported. The EPR spectra, electrochemical properties, absorption spectra, and luminescent properties of these radical adducts have been studied. All of them show electrochemical amphotericity being reduced and oxidized to their correspondin...

The initial reaction in bacterial carbazole degradation is catalyzed by carbazole 1,9a-dioxygenase, which consists of terminal oxygenase (Oxy), ferredoxin (Fd) and ferredoxin reductase components. The electron-transfer complex between reduced Oxy and oxidized Fd was crystallized at 293 K using the hanging-drop vapour-diffusion method with PEG 3350 as the precipitant under anaerobic conditions. ...

The title mol-ecule, C(15)H(13)NO, approximates a planar conformation except for the alkyl chain (ethyl group) bonded to the N atom with a maximum deviation from the least-squares plane through the 15 planar atoms of 0.120 (2) Å for the O atom. The distance of the formyl O atom from the plane of the carbazole ring is 0.227 (2) Å. The N-C bond lengths in the central ring are significantly differ...

Carbazole, discovered over 100 years ago, is a privileged heterocyclic motif whose electronic and structural features have allowed its derivatives to find numerous applications. In addition to its abundance in natural products and bioactive molecules, carbazole has been a key motif in the development of organic light-emitting materials because of its wide band gap, high luminescent efficiency, ...
