Abstract The study of interaction of shock waves and amino acid-based compounds offers valuable insights into the molecular interactions and processes essential for understanding the evolution of life on Earth. In this study, glycine picrate (GP) crystals were grown using the solvent evaporation solution growth method. The crystals were subjected to one to five consecutive shock pulses, and their structural, optical, dielectric, and morphological properties were systematically analyzed using powder X-ray diffraction (PXRD), UV-visible spectroscopy, dielectric spectroscopy, and optical microscopy. The XRD results revealed notable changes in diffraction peak intensities under shock-loaded conditions, with the second shock-loaded state showing enhanced crystallinity compared to both pristine and other shock-loaded conditions. However, increased shock pulses led to surface damage, reducing optical transparency. Dielectric analysis highlighted a significant enhancement in dielectric constant and a reduction in resistance in the second shock-loaded condition, indicating superior energy storage potential. These results are strongly correlated with structural improvements observed in the PXRD data. Despite the observed surface damage and reduced optical transmission for higher shock pulses, the second shock-loaded state demonstrated optimized properties for energy storage.
