Crystals of dibenzothiophen are monoclinic, a= 8·67 ± 1, b= 6·00 ± 1, c= 18·70 ± 2 A, β= 113·9°, Z= 4, space group P21/c. The structure was determined with Mo-Kα diffractometer data by Patterson, electron-density, and least-squares methods, the final R being 0·083 for 1176 observed reflexions.

Desulphurization of dibenzothiophene by bacteria
World Journal of Microbiology & Biotechnology, 1994Four out of 187 strains, from enrichment cultures of dibenzothiophene (DBT), grew on DBT or thiophene 2-carboxylate as S sources. The four isolates, presumptively identified as Agrobacterium sp., Xanthomonas sp. and Corynebacterium spp., individually and together desulphurized DBT, producing 2-hydroxybiphenyl and sulphate.

Dibenzothiophene-based oxalate derivatives were synthesized as type I photoinitiators, and their photoinitiation properties depend on the substituentpara-to-orthopositioning effect of the oxalates.

Biotransformation of dibenzothiophene to dibenzothiophene sulfone by Pseudomonas putida
Canadian Journal of Microbiology, 1989A strain of Pseudomonas putida was isolated that transforms dibenzothiophene (DBT) to DBT sulfone (DBT-5-dioxide) via DBT-5-oxide. It also degrades DBT to 3-hydroxy-2-formyl benzothiophene via an alternate and previously described pathway, and to an unidentified red crystalline compound.

A new dibenzothiophene-based dual-channel chemosensor for cyanide with aggregation induced emission
Journal of Photochemistry and Photobiology A: Chemistry, 2019A new dibenzothiophene-based barbituric acid derivative (DTB) with an aggregation induced emission (AIE) effect was synthesized as a naked-eye colorimetric and fluorescent probe for CN−.

Solid−Liquid Equilibria of Dibenzothiophene and Dibenzothiophene Sulfone in Organic Solvents
Journal of Chemical & Engineering Data, 2007This work reports the solid−liquid equilibria of several binary systems formed by solvent (1) + dibenzothiophene (2) and solvent (1) + dibenzothiophene sulfone (2). At least six experimental points were obtained to trace the solid−liquid equilibrium curve, using the visual technique to determine the change of phase.

The vibrations of dibenzothiophene
Spectrochimica Acta Part A: Molecular Spectroscopy, 1971Abstract Infrared spectra polarized along three orthogonal directions in single crystals of dibenzothiophene- h 8 and - d 8 have been recorded from 50 to 3500 cm −1 . The polarized Raman spectra of the single crystals have been measured in all possible orientations and this information has been supplemented by the measurement of depolarization ...
