An analysis of the industries for which wide implementation solar energy is currently considered relevant has been carried out. The aim study to build a methodology synthesis nanostructured pyrazoline dyes that can be used as coating material cells based on monocrystalline, polycrystalline and amorphous silicon, well development system evaluating effectiveness optimization this according target...

Transition metal complexes of Co(II), Ni(II) and Cu(II) metal ions with general stoichiometry [M(L)X]X and [M(L)SO(4)], where M = Co(II), Ni(II) and Cu(II), L = 3,3'-thiodipropionic acid bis(4-amino-5-ethylimino-2,3-dimethyl-1-phenyl-3-pyrazoline) and X = NO(3)(-), Cl(-) and OAc(-), have been synthesized and structurally characterized by elemental analyses, molar conductance measurements, magne...

Eight different derivatives of substituted 5-phenyl-1-(5-substituted phenyl) -4,5-dihydro1H-pyrazol-3-yl)-1H-tetrazole (4a-h) were synthesized by reacting the chalcones with hydrazine hydrate in presence of glacial acetic. The chemical structures were confirmed by means of FT-IR, H-NMR, mass spectra and elemental analysis. The compounds were screened for analgesic activity by acetic acid induce...

In the title compound, C21H20N2O3, the planes of the benzene ring and the naphthalene ring system are inclined to one another by 70.95°, and by 4.99 (6) and 75.93 (5)°, respectively, to the mean plane of the pyrazoline ring. The latter has an envelope conformation with the methine (CH) C atom as the flap. There is an intra-molecular O-H⋯N hydrogen bond that forms an S(6) ring motif. In the crys...
