Structural elucidation, hydrogen bonding motifs and solid state properties of p-toluenesulfonate salt of β-alaninine for optoelectronic device application

Abstract

Single crystal of β-alaninium p-toluenesulfonate (BAPT) has been grown by solvent slow evaporation method. Crystal structure of the title compound has been elucidated by single crystal XRD analysis. In structural analysis, chain and ring motifs lead to the hydrophilic layers at z = 0, 1/2 and 1 which is sandwiched between the hydrophobic layers at x = 1/4 and ¾. FTIR and FT-Raman spectra have been recorded to confirm the vibrational modes of the crystal. Optical behavior has been studied by UV–Vis–NIR analysis. Thermal properties of BAPT crystal has been investigated by TG-DTA measurements. Mechanical nature of material was studied through Vicker’s micro hardness studies. From dielectric measurements, relative dielectric permittivity values and theoretical values of polarizability values were determined. The third order NLO responses of BAPT has been analyzed by the Z-scan technique.
