New organic Stilbazolium cation Salt of 4‐[2‐(3 hydroxy‐phenyl)‐vinyl]‐1‐methyl‐pyridinium iodide (HMPI), which was obtained through solvent evaporation solution growth. The crystal structure was proved via the SC‐XRD technique. Its outcome reveals that the HMPI crystallised in a centrosymmetric pattern (P121/n1) and monoclinic crystal system. The compositional analysis was performed via 1H NMR and 13C NMR. The FT‐IR spectrum was used to determine the vibrational mode of the different molecular groups present in the material. The intermolecular interactions in the crystal structure were studied using Hirshfeld surface analysis. The molecular orbital energies (HOMO‐LUMO) and molecular electrostatic potential (MESP) were estimated using the Gaussian program with the density functional theory (DFT) method. The linear optical study revealed the transmittance percentage, lower cut‐off wavelength, and energy band gap for HMPI crystal. In the photoluminescence study, a green colour broad emission peak is observed at 521 nm. TG and DTA measured the thermal behaviour of grown HMPI crystal. Chemical etching and atomic force microscopy (AFM) experiments were used to report the surface properties of grown HMPI crystal. The Z‐scan technique, a He−Ne continuous wave laser at 632.8 nm used to measure the third‐order nonlinear optical susceptibility of the HMPI crystal. The Z scan approach reveals a saturable absorption and self‐defocusing nature of the title crystal.

“…For DSNA material, PL analysis was carried out for the liquid sample (methanol solvent) through the F7000 FL spectrophotometer at ambient temperature. Despite 530 nm being the cut‐off wavelength, for the PL analysis, 476 nm is used as the excitation wavelength based on the literature survey, considering the liquid state of the sample [26,48] . The obtained PL spectrum in the wavelength range of 500–700 nm is depicted in Figure 9.…”

The idea of incorporating a novel counter anion group with the organic stilbazolium cation (C16H19N2+) yields a new third harmonic generation active single crystal of 4‐[2‐(4‐Dimethylamino‐phenyl)‐vinyl]‐1‐methyl‐pyridinium 2‐Nitroaniline‐4‐sulfonate (DSNA). The slow evaporation solution growth technique is employed to obtain DSNA crystals, whose nonlinear responses are analyzed through a continuous wave laser Z scan experiment. The thermally induced strong reverse saturation absorption and self‐defocusing behaviour of DSNA crystal infers the aptness of the material as an optical limiting device. Optical characterization outcomes imply that the lower absorption edge falls in the visible region (530 nm), with a broad transparency range of 0.53 to 1 μm. Exploration of other optical constants, extinction coefficient (k = 10‐4), emission wavelength (620 nm – red light), optical (σopt = 1010 Ωm‐1) and electrical conductivity (σelc = 1011 Ωm‐1) also concludes that DSNA crystal is a possible applicant for optoelectronic devices. The various bonds and corresponding lengths and angles involved in the formation of DSNA ionic crystal are evaluated by means of the Single Crystal X‐Ray Diffraction (SCXRD) technique. Linear and nonlinear optical property findings undoubtedly affirm that the titular DSNA crystal is an effectual Nonlinear Optical (NLO) crystal.

The design and synthesis of three organic nonlinear optical crystals is presented for terahertz (THz) generation that incorporates the optimal characteristics of known organic nonlinear optical crystals 4‐(4‐(dimethylamino)styryl)‐1‐methylpyridinium 4‐methylbenzenesulfonate (DAST) and 2‐(4‐hydroxy‐3‐methoxystyryl)‐1‐methylquinolinium 2,4,6‐trimethylbenzenesulfonate (HMQ‐TMS). The three crystals feature the 4‐((4‐(dimethylamino)phenyl)ethynyl)‐1‐methylpyridin‐1‐ium (4DEP) cation and three different anion combinations. Gas phase ab initio calculations of the cation show that 4DEP has a larger hyperpolarizability than cations from both DAST and HMQ‐TMS. To obtain the molecular packing needed for large nonlinear optical susceptibility and efficient THz generation, three anions are tested that result in noncentrosymmetric crystals: 4‐methylbenzenesulfonate, 3‐nitrobenzenesulfonate, and napthalene‐2‐sulfonate. After synthesis and crystallization, the crystal structure is characterized via X‐ray diffraction (XRD) analysis, and the relative THz generation efficiency for ideal crystals is predicted. 4DEP‐N2S shows a roughly 30% larger relative second‐order nonlinear optical susceptibility compared to HMQ‐TMS and DAST and, therefore, shows promise as a new advanced THz generation crystal.
