In the title compound, C(29)H(30)N(2), the dihedral angle between the mean planes of the carbazole and the quinoline systems is 52.41 (6)°. Mol-ecules are linked into dimers by pairs of inter-molecular C-H⋯N hydrogen bonds and into a three-dimensional network by C-H⋯π inter-actions.

5,12-Dihydroindolo[3,2-a]carbazole is a promising scaffold for the design of visible light photoinitiators polymerization due to simultaneous presence two carbazole moieties that can be differently functionalized. Notably, redshift absorption spectra facilely obtained by nitration one carbazoles, second group being functionalized with various groups. Dinitration 5,12-dihydroindolo[3,2-a]carbazo...

In the title compound, C(12)H(7)I(2)N, the tricyclic aromatic ring system is essentially planar, with an r.m.s. deviation of 0.0272 Å. The two I atoms are marginally out of plane, with the C-I bonds angled at 3.9 (2) and 1.1 (2)° with respect to the planes of their respective benzene rings, above and below the plane of the carbazole ring system. No classical hydrogen bonds are observed in the c...

Three novel carbazole-based molecules have been synthesized and successfully applied as hole-transporting materials (HTMs) of CH3NH3PbI3-based perovskite solar cells. In particular, the perovskite cell with SGT-405, having a three-arm-type structure, exhibited a remarkable photovoltaic conversion efficiency (PCE) of 14.79%.

A tris(2,2'-bipyridine)cobalt(II)/(III) based polymer gel electrolyte has been successfully applied in conjunction with an organic carbazole dye in the construction of stable dye-sensitized solar cells with an energy conversion efficiencies of 8.7% and 10% at 1 sun and 0.1 sun light intensity.

In the title compound, C(12)H(13)N, two methyl-ene C atoms of the cyclo-hexene ring are disordered over two sites with occupancies of 0.591 (10) and 0.409 (10); both disorder components adopt half-chair conformations. The crystal structure is stabilized by inter-molecular N-H⋯π and C-H⋯π inter-actions.
