Isoflavone, Biochanin A, Dihydrobiochanin A, Phenylacetic acids, Fusarium javanicum After a lag-phase of 1 h a mycelial suspension of Fusarium javanicum completely degraded 5,7-dihydroxy-4'-methoxyisoflavone (biochanin A) to a series of transiently accumulating catabolites. The compounds were elucidated by spectroscopic techniques and are arranged in the first known degradative pathway for an i...

In the title compound, C20H14N2O2, the hy-droxy-benzene ring is almost perpendicular to the mean plane of the naphthalene ring system, making a dihedral angle of 85.56 (4)°. The 4H-pyran ring fused with the naphthalene ring system has a flattened boat conformation. In the crystal, O-H⋯N and N-H⋯O hydrogen bonds link the mol-ecules into a supra-molecular layer in the bc plane; N-H⋯π inter-action...

In this paper, 4-(dicyanomethylene)-2-t-butyl-6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) has been used in interface modification of dye-sensitized solar cells (DSCs) with combined effects of retarding charge recombination and Förster resonant energy transfer (FRET). DCJTB interface modification significantly improved photovoltaic performance of DSCs. I-V curves shows the conversion...

As a tropical country with biodiversity, Indonesia is rich flora especially those potential as medicinal plants such Jarak Kepyar (Ricinus communis). Leaves of jarak kepyar communis) are used medicine for wounds, rash, abscess, and fever. Therefore, the purpose this study was to determine active compound in ethanol n-hexane extract leaves using phytochemical analysis GC-MS. The research method ...

In the title compound, C(15)H(8)O, the asymmetric unit contains four independent mol-ecules and crystallizes with aromatic π-π stacking inter-actions[centroid-centroid distances = 3.5326 (18) Å].
