Synthesis, growth, structural, spectral and optical studies on 2-amino-4-picolinium 4-hydroxybenzoate single crystals

Abstract

2-amino-4-picolinium-4-hydroxybenzoate (2A4P4HB) were grown as crystals using a controlled evaporation method in the present study. The lattice parameters of 2A4P4HB were affirmed using X-ray diffraction measurements. Using 1H and 13C nuclear magnetic resonance spectral studies, the proton and carbon position was determined. Linear optical study was used to determine the cut off wavelength and the wide optical operating window. Thermogravimetric and Differential Thermal Analysis were used to examine their thermal response. Vickers microhardness testing was used to determine mechanical stability at room temperature. Meyer's law was used to investigate the hardness results. The Z scan measurements were performed on 2A4P4HB.
