Mutagenicity of phenanthrene and phenanthrene K-region derivatives
Mutation Research/Genetic Toxicology, 1979Phenanthrene and 9 K-region derivatives, most of them potential metabolites of phenanthrene, were tested for mutagenicity by the reversion of histidine-dependent Salmonella typhimurium TA1535, TA1537, TA1538, TA98 and TA100 and the rec assay with Bacillus subtilis H17 and M45.

Light gas solubility in phenanthrene: the hydrogen—phenanthrene and methane—phenanthrene systems
Fluid Phase Equilibria, 1990Abstract A variable volume equilibrium cell was used to study the hydrogen—phenanthrene and methane—phenanthrene systems. The data were taken along isotherms from 398.2 to 473.2 K and up to pressures of 25.23 MPa. Henry's constants and heats of solution were calculated for both systems.

Theoretical Molecular Design of Phenanthrenes for Singlet Fission by Diazadibora-Substitution.
Journal of Physical Chemistry A, 2020Based on the valence configuration interaction (VCI) model and quantum chemical calculations, we theoretically investigate the potential of diazadibora-substituted phenanthrenes [(BN)2-phenanthrenes] as novel singlet fission (SF) chromophores.

Photochemical rearrangement of diarylethenes: synthesis of functionalized phenanthrenes.
Organic and biomolecular chemistry, 2020A novel protocol for the synthesis of functionalized phenanthrenes through photocyclization of diarylethenes (DAE) under UV irradiation is proposed. The reaction proceeds through 6π-electrocyclization with the formation of a cyclic (closed) intermediate ...

Bioactivity-Guided Isolation of Cytotoxic Phenanthrenes from Spiranthes sinensis.
Journal of Agricultural and Food Chemistry, 2019Bioactivity-guided separation led to the isolation of six novel phenanthrenes, spiranthesphenanthrenes A-F (1-6), together with 19 known compounds, including seven phenanthrenes (7-13), one bibenzyl compound (14), five flavonoids (15-16 and 20-22), and ...

BN-Phenanthrenes: Synthesis, Reactivity, and Optical Properties.
Organic Letters, 2019Two series of BN-phenanthrenes, including the parental compounds, have been synthesized in an efficient manner from commercially available materials. Both parental BN-phenanthrenes are strongly fluorescent in solution.

Phenanthrene-9-carboxylic Acid
Acta Crystallographica Section C Crystal Structure Communications, 1997The title compound, C15H10O2, crystallized in the centrosymmetric space group C2/c. Hydrogen bonding is of the cyclic dimer type about a center of symmetry. The carboxyl H and O atoms are ordered. The phenanthrene core is almost planar and the dihedral angle between the core plane and the carboxyl group plane is only 1.8(1) degrees. The bay H atoms, H4

Phenanthrenes from Juncus effusus
Planta Medica, 2013A chemical investigation of the EtOAc-soluble fraction from the ethanol extract of the medullae of Juncus effusus led to the isolation of three new 9,10-dihydrophenanthrenes, juncuenins E-G (1-3); two new phenanthrenes, dehydrojuncuenins D-E (4-5); one new feruloylated glycoside (6); and one known 9,10-dihydrophenanthrene (7).
