In the title compound, C14H9Br4N, the tricyclic ring system is almost planar (r.m.s. deviation for the 13 non-H atoms = 0.017 Å) and the methyl C atom deviates from the mean plane of the ring system by 1.072 (17) Å. In the crystal, Br⋯Br contacts [3.636 (3) and 3.660 (3) Å] slightly shorter than the van der Waals contact distance of 3.70 Å are seen.

The title compound, C(16)H(17)N, is a carbazole derivative that has been designed and synthesized as a potential organic electronic device, such as an OLED. The tricyclic aromatic ring system is essentially planar, the two outer rings making a dihedral angle of 4.8 (1)°. No classical hydrogen bonds are observed in the crystal structure.

In the title compound, C(22)H(15)NO(3)S, the plane of the carbazole ring system forms a dihedral angle of 65.06 (4)° with the naphthalene ring system. In the crystal structure, a weak intra-molecular C-H⋯O inter-action is observed between the naphthalene ring system and the sulfonate group. Two weak inter-molecular C-H⋯O inter-actions are also observed.

In the title mol-ecule, C24H21NO2, the dihedral angle between the carbazole ring system [with a maximum deviation of 0.052 (2) Å] and the benzene ring is 38.6 (1)°. In the crystal, weak bifurcated (C-H)2⋯O hydrogen bonds link the mol-ecules into chains along [100].

In the crystal structure of the title compound, C(20)H(17)N(5), the two imidazole rings are twisted with respect to the carbazole plane, making dihedral angles of 55.8 (2) and 43.7 (2)°. The crystal structure is stabilized by weak C-H⋯N and C-H⋯π inter-actions.

A novel bipolar host 9-(4-(9H-pyrido[2,3-b]indol-9-yl)phenyl)-9H-3,9'-bicarbazole (pBCb2Cz) was prepared for high efficiency blue phosphorescent organic light-emitting diodes (PhOLEDs), a high triplet energy (ET) material, employing electron-deficient α-carboline. pBCb2Cz (ET = 2.93 eV) was effective as a host material for FIrpic- and FCNIrpic-based blue PhOLEDs, and highest quantum efficiencie...

Self-host heteroleptic green iridium(III) dendrimers have been designed and easily synthesized. Through tuning the carbazole dendron density, high efficiency is achieved using these dendrimers with a simple molecular structure as the emitting layer for the non-doped organic light-emitting diodes.

The tricyclic aromatic ring system of the title compound, C15H9Cl2N, is essentially planar (r.m.s. deviation = 0.002 Å). The two Cl atoms lie slightly out of the plane of the carbazole ring system, with the C-Cl bonds forming angles of 1.23 (8) and 1.14 (8)° with the plane. The acetylene group has a syn orientation with respect to the ring system. In the crystal, no weak hydrogen bonds nor any ...

As a result of copolymerization N-vinyl carbazole with styrene, the optically transparent copolymer was synthesized and regularities process, composition structure determined. The constant values were determined by Fineman–Ross method (r1=0.032, r2=5.5). It found that styrene shows higher activity than carbazole. parameters value microstructure reveled. obtained has sufficiently high light-refr...

Organic fluorescent nanofibrils were fabricated from a linear carbazole trimer and employed for expedient detection of nitroaromatic explosives (DNT and TNT) and highly volatile nitroaliphatic explosives (nitromethane).
