“…Thus, α-amino acids acquire active optical properties due to being chiral species and directing the crystallization to non-centrosymmetric spatial groups. Moreover, the dipolar nature of amino acids provides unique physical and chemical properties, making them promising candidates for NLO applications [ 16 , 17 ]. That is, the presence of the –COO − and –NH 3 + groups promotes the increase of the asymmetric polarizability of the organic material, providing asymmetry in the ground-state charge of the molecule, necessary for the development of second-order optical nonlinearity [ 12 , 18 – 20 ].…”

Nonlinear optical materials have been investigated recently due to their potential technological applications in information storage and communications. In this context, semi-organic crystals can effectively combine the desired nonlinear optical properties of amino acids with the promising mechanical and thermal properties of inorganic materials. In this work, we have synthesized and characterized a semi-organic crystal of the amino acid l-histidine and hydrofluoric acid and investigated the chemical interactions between the organic and inorganic moieties. The crystal of l-histidine bis(fluoride) has been produced by slow solvent evaporation and characterized by X-ray diffraction (XRD) crystallography and thermogravimetric and differential thermal analyses. The XRD conducted using the Rietveld method shows that the unit cell is orthorhombic with the P21212 space group and contains four l-histidine bis(fluoride) units. Both differential thermal analysis and temperature-dependent XRD show that the crystals are thermally stable up to 191°C and do not undergo phase transition. The computational Hirshfeld surface analysis of the crystal structure reveals the main intermolecular interactions. Density functional theory has been employed to calculate the ionic interaction energy and electrostatic potential maps and confirm the spontaneity of ionic association at 191°C. The combined experimental and computational results show that the thermal stability of the semi-organic l-histidine bis(fluoride) crystal makes it suitable for nonlinear optical applications in optical sensing and communication systems.

“…Due to this dipolar nature, glycine has promising physical properties. [17,18] Growth and characterization of glycine with sulfate, acetate, and other metal ions crystals has the talented materials for its extensive range of applications such as second harmonic generation, ultraviolet laser, and infrared sensors due to its high pyroelectric coefficient, optical transmission, and reasonably low dielectric constant. Single crystals such as triglycine sulfate, calcium dibromide bis(glycine) tetrahydrate, sodium acid phthalate, diglycine hydrochloride, etc., have been explored for their significant nonlinear optical, dielectric, piezoelectric, pyroelectric and ferroelectric properties.…”

Triglycine oxalate single crystal is grown by a slow evaporation technique from the saturated solution at the predetermined temperature. X‐ray diffraction studies of the grown crystal reveal that the grown crystal belongs to a monoclinic structure. The presence of elements and various functional groups of the triglycine oxalate is found in the Fourier transform infrared analysis. Optical transparency of the grown crystals is found to have the maximum transparency in the entire visible region. Thermogravimetric analysis shows that the grown crystals have three stages of decomposition. The microhardness of the grown crystals exhibits that the crystal is a soft material. The electrical studies such as dielectric constant, and dielectric loss are determined for the frequency range from 100 Hz to 200 kHz at different temperatures.
