1-Phenyl-3-(4-nitrophenyl)-5-(2-thienyl)-2-pyrazoline was synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction. UV-Vis spectra and fluorescence spectra were measured. Density functional theory calculations on the structure of the title compound were performed at the B3LYP/6-311G** level of theory. NPA atomic charge distributions indicate that, although th...

In the title compound, [Fe(C(5)H(5))(C(23)H(21)N(2)S(2))], the cyclo-penta-dienyl rings of the ferrocenyl unit deviate slightly from the eclipsed form. In the pyrazoline ring, the N atom bonded to S-benzyl dithio-carbazate exhibits unconventional sp(2)-hybrid character in order to form an extended conjugated system. The pyrazoline ring displays an envelope conformation. The mol-ecules are linke...

The development of highly efficient plastic scintillators for neutron/gamma pulse shape discrimination is a matter current interest. This generally achieved using two fluorophores, with one them being added to the polymer formulation at concentration higher than typically 15 weight percent (wt%). Here, we report our results concerning performant poly(vinyltoluene)-based (PVT) fast discriminatio...
