To examine the effect of N,N-dimethyl substitution on the formation of those solvation structures, we measured the ACN mole fraction dependence of FT-IR spectra and the angle χ dependence of IR electroabsorption (∆A) spectra of DMPNA in ACN/C2Cl4. Here χ is the angle between an ...

The selective recognition of compound 1 to aromatic compounds was investigated through fluorescence, 1H NMR titrations, HRMS and IR spectra. The experimental results indicated that 1 can distinguish effectively p-nitroaniline (p-NA) from other aromatic compounds. Graphical abstract A new chemodosimeter ...

nonlinear optical materialA triphenylmethane-4-nitroaniline salt has been synthesized and the crystals have been grown by using slow evaporation solution growth technique. The grown single crystal was investigated by recording the powder XRD, FT-IR spectrum, UV-Vis spectrum, Vickers microhardness test,...
The resulting polyaniline-copper composites were studied by IR spectroscopy, atomic force microscopy, and X-ray diffraction analysis. The more drastic increase in the rate of hydrogenation of p -nitroaniline and its conversion (compared with those of the electrochemical process on the Cu cathode) ...
