“…In recent years, complexes of amino acids with organic and inorganic acids possess excellent NLO properties [1][2][3][4][5][6]. Amino acids are interesting materials for NLO applications, it contains an asymmetric carbon atom so it is optically active and most of them crystallize in noncentrosymmetric space groups.…”

“…Among these materials, l-leucine is an interesting molecule from both the crystal engineering and supramolecular point of views. The l-leucine based semiorganic crystal has attracted much attention because it has a higher second-harmonic generation efficiency than potassium dihydrogen phosphate (KDP) [19][20][21][22][23][24]. l-Leucinium perchlorate (LLPCl) is a new material, first discovered by Jan Janczak and Genivaldo Julio Perpetuo, which is two times more nonlinear than KDP [25].…”

An amino acid based semiorganic nonlinear optical family single crystal of l-leucinium perchlorate (LLPCl) was grown by the solvent evaporation method at ambient temperature. Good optical quality single crystals up to a size of 6 mm × 5 mm × 3 mm were obtained. The single-crystal XRD analysis shows that the grown crystals have a monoclinic structure. Fourier transform infrared (FTIR) spectral analysis and UV-vis spectral studies were also carried out. Microhardness mechanical studies show that the hardness number (Hv) of a LLPCl single crystal decreases with the load as measured by the Vickers microhardness method. The dielectric properties of the grown crystal were analysed by varying the frequency. Photoconductivity analysis gives the variation of the photocurrent and dark current. The nonlinear optical properties were studied using the Kurtz and Perry powder method and the second harmonic generation efficiency was found to be 2.6 times higher than that of KDP crystals.

“…The interest in the synthesis and characterization of semiorganic crystals has increased in recent decades due to their nonlinear optical (NLO) properties and their potential for application in frequency conversion, optoelectronic devices, data storage, etc. . Semiorganic crystal have been explored and considered to be promising for such application because it can incorporate good properties of both organic and inorganic crystals, such as high NLO properties from the organic crystal and high mechanical straight from the inorganic crystal.…”

Semi organic crystals have been intensively studied aiming applications in nonlinear optical (NLO). Such applicability requires crystals with both high quality and thermal stability, which make the full characterization of this material a topic issue. In this paper, single crystals of L-isoleucine hydrochloride monohydrated (L-Ile.H2O.HCl) was synthesized by slow evaporation technique and characterized by thermal analysis and X-ray diffraction (XRD) measurements. XRD results at 298 K showed that the sample crystallize with the orthorhombic structure, and the lattice parameters obtained by Rietveld refinement were a = 5.873(3)Å, b = 24.814(4)Å, and c = 6.873(5)Å. Thermal analysis measurements shows four decomposition stages between 328 -480 K which were associated with loss of water by desolvation, loss crystallization water and decomposition of L-Ile.HCl. XRD measurements as a function of temperature up to 428 K show an irreversible phase transformation. This transformation was obtained after 32 hours keeping the L-Ile.HCl.H2O sample at 413 K. The analysis shows that phase transformation occurs due to water and chlorine losses without destroy the amino acid carbon chain and in the end of transformation only the precursor amino acid remains. L-Ile.HCl.H2O present low thermal stability and the phase transformation is time and temperature dependent.
