“…Advances in Optical Technologies 7 The criteria for SHG may also be satisfied by centrosymmetric molecule if they aggregate in a noncentrosymmetric manner and there is a contribution to the bulk susceptibility from intermolecular charge transfer [5]. Most molecules like paranitro aniline have very large SHG at the molecular scale due to the charge transfer from the donor to the acceptor crystallize in a centrosymmetric lattice due to predominating antiparallel -stacking between the aromatic rings as a consequence of dipolar interactions [38,39].…”

“…According to crystal engineering, second harmonic generation occurs mostly in noncentrosymmetric crystals due to nonzero hyperpolarizability. But some of the recent reports of organic molecular complexes like caffenium picrate [5], picolinium maleate [6], guanidinium trifluoroacetate, and so forth have highlighted that even centrosymmetric crystals possess SHG effect due to the presence of delocalized electron system linking donor and acceptor groups which enhance the necessary asymmetric polarizability [7,8]. The various organic subnetworks enhance the thermal and mechanical stabilities through hydrogen bonding interactions and behave as noncentrosymmetry material in the bulk [9,10].…”

A new organic charge transfer molecular complex salt of benzimidazolium salicylate (BSL) single crystals was grown by the slow evaporation solution growth technique using methanol as a solvent at room temperature. The grown crystals were characterised by single crystal X-ray diffraction (XRD) which confirms that the crystal belongs to monoclinic system with the centrosymmetric space group P2 1 / . The crystalline perfection of the grown crystal was analyzed by high resolution X-ray diffraction (HRXRD). The presence of various functional groups was identified by FTIR spectrum. UV-Vis spectral study reveals that the BSL crystal is optically transparent in the wavelength region 342 nm-1100 nm. Dielectric measurements of the crystal at various frequencies were also determined. The mechanical properties of the grown crystal were assessed using Vickers microhardness testing. Nonlinear optical property of the crystal was confirmed using Kurtz and Perry powder technique and the SHG efficiency of the BSL crystal is 0.7 times greater than that of the standard KDP crystal.

“…The organic nonlinear optical materials are having good NLO and electro-optical susceptibility in comparison with inorganic counterparts [9]. Organic compounds likeL-histidinium 2 nitrobenzoate [10], caffenium picrate [11], picolinium maleate [12], guanidiniumtrifluoroacetate [13], L-histidinium 2 nitrobenzoate etc have shown higher second harmonic generation efficiency than various inorganic crystals.…”
