A critical study of crystal structure, N—H—Br interaction, effect of charge transfer on third-order nonlinear optical properties and optical limiting behaviour of a new crystal: (4-Methoxyphenyl) methanaminium bromide

A new crystal, (4-Methoxyphenyl) methanaminium bromide (4MPMAB) was successfully developed by suitably functionalising the counter anion for nonlinear optical applications. Structural analysis was carried out and explores the monoclinic crystal system of P21/c space group. The methoxy group of the cation is co-planar with the phenylene moiety with an r.m.s deviation of 0.0294 ? from the mean plane (C1–C8/O1). The donor mesomeric effect of methoxy group is revealed. The strong bonding nature and intermolecular N–H—Br interaction between the ammonium cation and the halide anion are evidenced. In addition to that, C–H—Br and C–H—π interactions are also observed. As the protonation takes place by the hydrogen of hydrobromic acid (HBr), the contribution of HBr is highlighted in the formation of the 4MPMAB crystal. Powder X-ray diffraction (PXRD) study authenticates the good crystalline nature of the sample. Fourier transform infrared (FT-IR), 1H and 13C Nuclear magnetic resonance (NMR) spectral study ascertained the functional groups, the formation of the molecule and the N–H—Br interaction of the grown crystal. The crystal is stable up to 219 °C. 4MPMAB has soft nature. The crystals have 65% optical transmission from 330 nm to 1100 nm with estimated optical band gap value of 3.5 eV. Z-scan study exhibits the higher third-order nonlinearity of 4MPMAB crystal. The influence of charge transfer on third-order nonlinear optical properties were revealed. Further, the optical limiting performance of 4MPMAB crystal has also been investigated.

Nucleophilic substitution reactions of N-methyl α-bromoacetanilides with benzylamines in dimethyl sulfoxide

Kinetic studies of the reactions of N-methyl-Y-a-bromoacetanilides with substituted X-benzylamines have been carried out in dimethyl sulfoxide at 25.0 °C. The Hammett plots for substituent X variations in the nucleophiles (log kN vs σX) are slightly bipha
