The title compound, C(21)H(21)NO, consists of a carbazole skeleton with a meth-oxy-benzene ring fused to the carbazole, and a butyl group attached to the carbazole N atom. The carbazole skeleton is nearly planar [maximum deviation = 0.078 (2) Å], and it is oriented at a dihedral angle of 4.22 (4)° with respect to the adjacent meth-oxy-benzene ring.

The first report on the fabrication and application of a nanocomposite containing poly-N-vinyl carbazole (PVK) polymer and graphene oxide (GO) as an antimicrobial film was demonstrated. The antimicrobial film was 90% more effective in preventing bacterial colonization relative to the unmodified surface. More importantly, the nanocomposite thin film showed higher bacterial toxicity than pure GO-...

The solution-processable small molecules based on carbazole or fluorene containing rhodanine dyes at both ends were synthesized and introduced as acceptors in organic photovoltaic cells. The high energy levels of their lowest unoccupied molecular orbitals resulted in a power conversion efficiency of 3.08% and an open circuit voltage of up to 1.03 V.

Carboxylated pyrrole (Pyr, a index)- and carbazole (Cbz, b index)-containing monomers 6-7a/b and 9a/b have been readily synthesized from the monobenzyl ester of L-glutamic acid and triamine 2 using Clauson-Kaas and amide coupling reactions. In contrast to Pyr-containing compounds 6-7a, and 9a, the three Cbz-containing monomers 6-7b, and 9b have been found electroactive and were successfully ele...

A series of novel platinum-containing carbazole monomers and polymers was synthesized and fully characterized by UV-VIS absorption, luminescence, and photoinduced absorption studies. In these compounds, a carbazole unit is incorporated into the main chain via either a para- or a meta-linkage. We discuss the effects of linkage and polymerization on the energy levels of S1, T1, and Tn. The S1-T1 ...

Indolo[3,2-b]carbazole-based hole transporting materials (HTM1–3) are developed for dopant-free perovskite solar cells (PSCs). The newly synthesized compounds studied as alternatives of conventional hole-transporting which typically require additives, characterized by low resistivity to penetration water, complicated synthesis and purification. influence substituents derivatives indolo[3,2-b]ca...

A carbazole-based triple bridging ligand (LH) consisting of two imidazole moieties at 3,6 positions with a diketone unit at the carbazole nitrogen forms carbazole-bridged zinc(II) complexes with structures of [(L(-))4(Zn(2+))n] (n = 2-6), where the strength of aromatic stacking interactions between the carbazole rings increases with an increase in the number of Zn(2+) ions bridged by the imidaz...

The synthesis, structure and biological activity of carbazole compounds has been long focus of research interests in the field of medicinal chemistry. 5,8-dibromo-5,6-dihydro(3,2-a)carbazole A have prepared in good yield by a free radical bromination reaction of 8-bromo-5,6-dihydro9(3,2-a)carbazole with N-bromosuccinimide in carbontetrachloride at ambient temperature.. Compound 2 have prepared ...

The last two decades had witnessed extensive investigation on bacterial degradation of carbazole, an N-heterocyclic aromatic hydrocarbon. Specifically, previous studies have reported the primary importance of angular dioxygenation, a novel type of oxygenation reaction, which facilitates mineralization of carbazole to intermediates of the TCA cycle. Proteobacteria and Actinobacteria are the pred...
