“…Protonation of the amino acid on the N1 site is reflected in the N1-C2-C3 and N1-C2-C1 angles which vary in the range 117.7 (2) and 121.8 (2) . This also occurs with other salts of toluidinium derivatives (Mohana Priyadarshini et al, 2013).…”

Three new proton transfer compounds, [2-ammonio-5-methylcarboxybenzene perchlorate (1), (C8H10NO2(+)·ClO4(-)), 4-(ammoniomethyl)carboxybenzene nitrate (2), (C8H10NO2(+)·NO3(-)), and 4-(ammoniomethyl)carboxybenzene perchlorate (3), (C8H10NO2(+)·ClO4(-))], have been synthesized, their IR modes of vibrations have been assigned and their crystal structures studied by means of single-crystal X-ray diffraction. Their asymmetric units consist of one cation and one anion for both compounds (1) and (2). However, the crystal structure of compound (3) is based on a pair of cations and a pair of anions in its asymmetric unit. The three-dimensional Hirshfeld surface analysis and the two-dimensional fingerprint maps revealed that the three structures are dominated by H...O/O...H and H...H contacts. The strongest hydrogen-bonding interactions are associated with O-H...O and N-H...O constituting the highest fraction of approximately 50%, followed by those of the H...H type contributing 20%. Other close contacts are also present, including weak C...H/H...C contacts (with about 10%).

This review delves into the nonlinear optical characteristics of crystals derived from picric acid, providing a comprehensive analysis of their unique properties and potential applications in the realm of nonlinear optics. Picric acid, with its distinctive molecular structure, has been widely explored for its nonlinear optical behaviour, making it a fascinating subject for research and development. The review begins by elucidating the fundamental need and significance of crystal growth. The summary of preparation, spectral analysis and nonlinear optical characteristics and the significance of picric acid as a promising material in this domain is also discussed. The interpretation of nonlinear behaviour in optical properties of various compounds of picric acid is reviewed and discussed. The structural data of aminoacidic picrate crystals in the field of non-linear applications are reviewed. The conceptual background of nonlinear optical properties is well deliberated and used in order to have a better knowledge of the optical behaviour of the picrate crystals. UV-VIS spectroscopy and Second harmonic efficiency of picric acid compounds are also briefly discussed. In conclusion, this review provides a comprehensive overview of the nonlinear optical performance of picric acid-based crystals, offering valuable insights for researchers, scientists, and engineers working in the field of nonlinear optics.

“…Light passing through any NLO material gets altered which depends on its temperature, orientation and wavelength of the light etc [5][6][7]. The organic materials with inclusion of aromatic ring are highly suitable for χ (2) (second-order) and χ (3) (third-order) NLO applications since their high optical damage, higher nonlinearity and ultrafast or electronic response [8]. There is a huge ultimatum, for novel NLO materials with large NLO figures of merit that are widely used as they possess good stability, large laser damage threshold with low mechanical strength.…”

“…Mulliiken approach is based on the interactions of transfer of charge from the two aromatic molecules which arises out of electron transfer of complex of Lewis base to Lewis's acid. Generally, visible region's laser radiation gets absorbed when there is an interaction between e-(electron) donor and e-acceptor molecules which further leads to the origin of intensely colored charge transfer complexes [8,11]. Organic NLO crystals are too difficult to grow a large crystal than inorganic crystals because of weak intermolecular binding energy [12].…”

Bulk size of urea barbituric acid single crystal which have not been reported earlier was successfully grown by slow evaporation solution growth method. Single-crystal XRD brought out the lattice constant and the crystal system is observed to be monoclinic with space group P. Functional group of UBA were determined by FT-IR. Title crystal is entirely visible from 270 to 900 nm with linear optical energy gap value to be 4.50 eV. The observed HOMO-LUMO energy gap was 5.21 eV. Thermally, UBA crystal is found to be stable up to 184˚C. The Cp value of UBA increases from 1.21 to 1.58 J/gK with the temperature difference from 30 to 100˚C. UBA shows good photoconductive nature and it found to be positive and Laser Damage Threshold (LDT) value of UBA crystal is 0.97 GW/cm2. Hardness testing confirms that UBA crystal belongs to soft nature category. Dielectric properties of UBA crystal are studied as a function of frequency and temperature. Third order NLO properties of the UBA crystal were studied under CW and pulsed lasers (ns) regimes using Z-scan technique. Good Optical limiting (OL) response confirms the efficiency of UBA crystal to be used as optical limiters for protection towards short pulse lasers.
