In the title compound, C26H19BrN2O5S, the carbazole tricycle is essentially planar, with the largest deviation being 0.126 (3) Å for the C atom connected to the nitro-phenyl group. The carbazole moiety is almost orthogonal to the benzene rings of the adjacent phenyl-sulfonyl and nitro-phenyl groups, making dihedral angles of 85.43 (15) and 88.62 (12)°, respectively. The mol-ecular conformation ...

Functionalising 2,5-di(N,N'-carbazolyl)terephthalonitrile or 2,3,5,6-tetra(N,N'-carbazolyl)terephthalonitrile on the carbazole moiety with alkoxy chains, gives a family of materials that show TADF response; two them are also liquid crystalline.

In the title compound, C28H24N2O7S, the carbazole system is essentially planar, with a maximum deviation of 0.0644 (19) Å for the C atom connected to the 4,5-dimeth-oxy-2-nitro-phenyl group. The dihedral angle between the carbazole moiety and the dimethoxy-substituted nitrophenyl ring is 58.55 (7)°. The sulfonyl group forms two intra-molecular C-H⋯O bonds with the adjacent carbazole system, for...

In the sterically hindered title compound, C26H17ClN2O6S, the carbazole ring has a maximum deviation from planarity of 0.067 (4) Å for the C atom connected to the aldehyde group. The carbazole moiety forms a dihedral angle of 72.8 (1)° with the nitro-substituted benzene ring. The O atom of the meth-oxy group deviates by 0.186 (1) Å from the adjacent carbazole moiety. The phenyl-sulfonyl group f...

Colorless transparent single crystals of trilanthanum hexa-silicon undeca-nitro-gen, La3Si6N11, were prepared at 0.85 MPa of N2 and 2273 K. The title compound is isotypic with Sm3Si6N11. Silicon-centered nitro-gen tetra-hedra form a three-dimensional network structure by sharing their corners. Layers of one type of SiN4 tetra-hedra and slabs composed of the two different La(3+) cations and the ...

5,12-Dihydroindolo[3,2-a]carbazole is a polycyclic structure combining in its scaffold two carbazole moieties sharing fused aromatic ring. Since the pioneering works reported 2019 on this concerning substitution of carbazoles by similar functional groups, no recent investigation has been devoted to asymmetrize carbazoles. In work, series 13 compounds based 5,12-dihydroindolo[3,2-a]carbazole pre...

The effect of flexible tetra-methylene vs. semi-rigid xylylene spacers appended in two quinoline tagged sensors bqbpbn (1) and bqbpxn (2) on the sensing nitro-phenolic compounds metal ions has been demonstrated.

In the title compound, [NiCl(2)(C(14)H(32)P(2))]·2C(12)H(9)N, the neutral [Ni(dppe)Cl(2)] complex [dppe is 1,2-bis-(diisopropyl-phosphan-yl)ethane] consists of a tetracoordinated Ni(2+) cation and has a crystallographic twofold axis passing through the metal atom and the mid-point of the CH(2)-CH(2) bond of the dppe ligand. The metal atom shows slight tetra-hedral distortion from an ideal squar...

The title compounds, C30H18N2O5S, (I), and C27H18N2O4S2, (II), are carbazole derivatives with a phenyl-sulfonyl group and a nitro-phenyl group attached to the carbazole moiety in identical positions in both mol-ecules. A benzo-furan ring system in (I) and a methyl-thio-phene ring in (II) are fused with the respective carbazole moieties on the same sides. The mean plane of the carbazole ring sys...
