Computational Investigations about the Ground and Excited States’ Properties of Trans-4-N,N-Dimethylamino-4’-Nitro-Stilbene (DNS) and Trans-4-N,N-Dimethyl-Amino-4’-Cyanostilbene (DCS) Derivatives

During the past several years, the field of electro optical organic and nonlinear optical material has received extensive attention [1-3] because of their possible application as fluorescence probes, electro optical switches and chemical sensors. Due to the electron donating and accepting groups on opposite sides, such material, which is connected by a highly delocalized electron system, is imp...

Acoustical Studies of Some Derivatives of 4-Amino Benzoic Acid in 1, 4-Dioxane and Dimethyl Formamide at 308.15 K

The ultrasonic velocity, density and viscosity of some Schiff bases of 4-amino benzoic acid  were measured in 1,4-dioxane and dimethylformamide at 308.15 K. Various acoustical properties such as isentropic compressibility (ks), Rao’s molar sound function (Rm), the Van der Waals constant (b), molar compressibility (W), inter molecular free len...

4-{[4-(Dimethylamino)benzylidene]­amino}-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one

The azomethine double-bond in the title Schiff base, C(20)H(22)N(4)O, has an E-configuration. The aromatic ring of the benzyl-idene portion (r.m.s. deviation 0.011 Å) and the five-membered pyrazolyl ring (r.m.s. deviation 0.033 Å) form a dihedral angle of 19.0 (1)°. The phenyl substituent is twisted by 55.0 (1)° with respect to the five-membered ring.

In the title compound, C(14)H(16)BrNO(5), the isoxazolidine ring adopts an envelope conformation, with the N atom at the flap. In the crystal, inter-molecular C-H⋯N and C-H⋯O hydrogen bonds generate R(3) (3)(18) ring motifs which are fused into a ribbon-like structure extending along the b axis.
