Four new D-pi-D (or D-pi-D-pi-D) complexes 9-ethyl-3-E-((1-ferrocenyl)vinyl)-carbazole (1), 9-ethyl-3,6-E,E-((1,1-diferrocenyl)vinyl)- carbazole(2), 10-ethyl-3-E-((1-ferrocenyl)vinyl)-phenothiazine (3), 10-ethyl- 3,7-E,E- ((1,1-diferrocenyl)vinyl)-phenothiazine (4), have been obtained by solid-phase Wittig reactions and fully characterized. The four complexes were treated with iodine leading to...

The nucleotide sequences of the 27,939-bp-long upstream and 9,448-bp-long downstream regions of the carAaAaBaBbCAc(ORF7)Ad genes of carbazole-degrading Pseudomonas sp. strain CA10 were determined. Thirty-two open reading frames (ORFs) were identified, and the car gene cluster was consequently revealed to consist of 10 genes (carAaAaBaBbCAcAdDFE) encoding the enzymes for the three-step conversio...

Carbazole derivatives [1-6] have been reported to exhibit pharmacological properties like anti­ tumour, anticonvalsant, psychotropic, antiinflam­ matory, antihistamine and antibiotic properties. Oxazole derivatives [7-15] have been used as optical whitening agents, sensitizing dyes, photoreducing pigments, muscle relaxant and effective against wide range of enteric infections, appetite depressa...

In the paper by Hong, Song & Wu [Acta Cryst. (2007), E63, o2296], the scheme shows the wrong structure. The correct scheme is shown below and the compound name is corrected to "poly[[di-μ(2)-aqua-diaqua-hemi-μ(6)-oxalato-barium(II)] 2,4,6-trinitro-phenolate monohydrate", {[Ba(C(2)O(4))(0.5)(H(2)O)(4)]C(6)H(2)N(3)O(7)·H(2)O}(n).[This corrects the article DOI: 10.1107/S1600536807038159.].

Organometallic materials that exhibit white luminescence in condensed phases are of considerable interest for lighting and display applications. Herein, new carbazole-based Au(I) complexes containing an isocyanide group a long pentyl chain were synthesized. The complex with unsubstituted carbazole moiety exhibited emission at room temperature as well nematic liquid crystalline behavior. Color t...

A linear coplanar carbazole-based benzoxazole derivative without any auxiliary moieties could gelatinize organic solvents, and exhibited emission enhancement owing to the J-aggregate formation.

The synthesis of several carbazole-bis(triazole) (CzTrR) and carbazole-bis(tetrazole) (CzTR) ligands (5a–d 6a–d, respectively, where R=Me (a), i–Pr (b), Bz (c) CH2-2,4,6-C6H2Me3 (d)) is reported. Reaction these with PdCl2 in refluxing acetonitrile affords the complete series square planar complexes, Pd(CzTrR)Cl (7a–d) Pd(CzTR)Cl (8a–d). analogous platinum complexes are prepared by deprotonation...

In the title compound, C(27)H(26)N(2)O, the mean planes through the carbazole and quinoline ring systems form a dihedral angle of 67.23 (5)°. Mol-ecules are linked into cyclic centrosymmetric dimers by O-H⋯N hydrogen bonds, and C-H⋯π inter-actions with the pyridine ring of the quinoline ring system as an acceptor. The dimers are linked through C-H⋯O hydrogen bonds.
