meso-Anthriporphyrin is a carbaporphyrinoid with an anthracene ring embedded in the tripyrrolic framework. The coordination of palladium(II) results in a specific intramacrocyclic metal(II)-η(2)-CC interaction which facilitates the cleavage to palladium(II) acyclic oligopyrrole with the appended anthracene moiety.

The health implication of PAHs has been great concern due to its contamination the food chain. This study was carried out identify challenges associated with bioaccumulation in Fluted Pumpkin (Telfairia occidentalis) and Waterleaf (Talinum fruticosum) along Imo River Watershed, State, Nigeria. A total 8 soil samples (0-30cm) were randomly collected from different activity areas on watershed ana...

Umbelliferone, a phenolic coumarin and dietary agent is believed to play a key role in pharmacological activities including anti-cancer and anti-oxidants effect in various in vitro and in vivo models. In present data on the pre-treatment of umbelliferone (30 mg/kg b.w.) for 16 weeks to 7,12-dimethylbenz(a)anthracene induced hamsters provides protection on cellular integrity by observing the sta...

Dibenz[a,h]anthracene (DB[a,h]A) and its microsomal metabolites, trans-3,4-dihydro-3,4-dihydroxydibenz[a,h]anthracene (DBA-3,4-diol), trans,trans-3,4:8,9-tetrahydro-3,4:8,9-tetrahydroxydibenz[a,h]anth racene, trans,trans-3,4:10,11-tetrahydro-3,4:10,11-tetrahydroxydibenz[a,h] - anthracene (DBA-3,4,10,11-bis-diol) and trans,trans-3,4:12,13-tetrahydro-3,4:12,13- tetrahydroxydibenz[a,h]anthracene w...

The photodimerization and thermal dissociation kinetics of anthracene derivatives corresponding photodimers are related to the substituent chemical structures.

In the title compound, C(16)H(14)O, the asymmetric unit consists of three crystallographically independent mol-ecules. The anthracene units are essentially planar, with maximum deviations of 0.165 (1), 0.153 (1) and 0.045 (1) Å in the three mol-ecules. In the crystal structure, mol-ecules are linked via inter-molecular C-H⋯O hydrogen bonds. Further stabilization is provided by C-H⋯π inter-actions.

Numerical methods to predict the solubility of anthracene in mixed solvents have been proposed. A minimum number of 3 solubility data points in sub-binary solvents has been employed to calculate the solvent-solute interaction terms of a well established colsolvency model, i.e. the combined nearly ideal binary solvent/Redlich-Kister model. The calculated interaction terms were used to predict th...

In the title Schiff base, C21H14N4O4, the dihedral angle between the two nitro groups and the central benzene ring are 83.6 (5) and 2.6 (6)°. The anthracene ring system and the benzene ring make a dihedral angle of 0.7 (2)°. Intra-molecular N-H⋯O and C-H⋯N hydrogen bonds occur. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules, forming chains along the b-axis direction.
