The effects of two different metal oxide catalysts, SnO and Li2O, on the dehydrogenation temperature Carbazole N-Ethylcarbazole (NE), respectively, were investigated by Thermogravimetric analyzer Differential Scanning Calorimetry. experiments performed with 10wt% Li2O added to N-Ethylcarbazole, compared pure N-Ethylcarbazole. results showed that was lower than Carbazole, +SnO lowest, is an idea...

The title compound, C(14)H(9)N, is the second crystallographically characterized example of an ynamine with an H atom in the C-terminal position. There are two independent mol-ecules (A and B) in the asymmetric unit. The structures of both mol-ecules are essentially planar (r.m.s. deviation = 0.0312 and 0.0152 Å). The N-C(sp) bond lengths are 1.353 (4) and 1.350 (4) Å, and those of the acetyl-e...

Luminescent radicals are gathering constant attention as a new class of luminescent material due to the ground and excited state doublet character. In their Research Article (e202302550), Ken Albrecht co-workers report carbazole dendronized tris(2,4,6-trichlorophenyl)-methyl (TTM) radical. Dendron modification increases photostability photoluminescence quantum yield up 63 % in cyclohexane. The ...

The protonation of carbazole derivatives results in the restriction intramolecular rotation, planarization molecule and relocalisation LUMO orbital increasing fluorescence quantum yield from 16% to 80%.

Two novel BODIPY (pyrromethene, PM) dyes containing N-ethyl carbazole at the meso position are synthesized and their photophysical properties in different solvents and the photochemical stabilities and laser performances in n-heptane are investigated. The n-heptane solution of the dyes was used as a gain medium in a constructed narrow band dye laser, pumped by a Q-switched (10 Hz) frequency-dou...

Glioblastoma multiforme (GBM) is the most fatal form of human brain cancer. Although temozolomide (TMZ), an oral alkylating chemotherapeutic agent, improves the survival rate, the prognosis of patients with GBM remains poor. Naturally occurring carbazole alkaloids isolated from curry leaves (Murraya koenigii Spreng.) have been shown to possess a wide range of anticancer properties. However, the...

Most conventional anticancer drugs exert either anti-proliferation or anti-angiogenesis activity. Recently, searching for potential multi-target agents has become an alternative strategy for cancer treatment. Several structurally different carbazole alkaloids from either natural or synthesized sources represent an important and heterogeneous class of anticancer agents. In the present study, we ...

A copper(II)-mediated regioselective N-arylation of azoles has been developed using 8-aminoquinoline amide as a directing group. This reaction shows a broad substrate scope with different azoles such as pyrroles, indoles, pyrazoles and carbazole with good yields.

A synthetic method for the preparation of 6-aryl-1,4-dimethyl-9H-carbazoles involving a palladium catalyzed coupling reaction of 1,4-dimethyl-9H-carbazole-6-boronic acids and (hetero)aryl halides is described.
