“…The best prospects for exposing a material's intrinsic qualities are single crystals. Organic bulk crystalline materials with specific orientations [ 1 , 2 ] have attracted more attention in micro-electronics, thermoelectrics, optical communications, optoelectronics and scintillators [ [3] , [4] , [5] , [6] ]. The economy, simple synthesis routes and easy structural modifications of organic crystals have made them suitable for industrial applications.…”

“…They are also found in many synthetic crystals and materials used in various technological applications. Generally, centrosymmetric crystals do not exhibit second harmonic generation efficiency (SHG); however, they give rise to third-order nonlinear behavior [4,5]. Third harmonic generation (THG) is a nonlinear optical process in which three photons with the same frequency interact within a material, resulting in the generation of a new photon with triple the frequency (three times the energy) of the incident photons.…”

In this article, we discuss the preparation of organic 2-chloro-5 nitroaniline (2C5NA) crystals and their different kinds of physical, chemical, and mechanical properties. The vertical Bridgman approach was used to effectively produce the bulk organic 2C5NA crystal. To produce a good-quality bulk crystal, the shape, dimensions, and cone angle of the ampoule were optimized. Also, the temperature profile was set for the 2C5NA crystal. The growth atmosphere and the lowering rate were identified to obtain a homogeneous mixture of the compounds and initiate the nucleation process. Single-crystal X-ray diffraction (XRD), powder XRD, proton Fourier transform nuclear magnetic resonance (FT-NMR), and Fourier transform infrared investigations were used to confirm the crystal structure, molecular structure, and presence of functional groups in the formed crystal. The formed crystal has a monoclinic crystal structure with the space group P21/c, according to single-crystal XRD analysis. The thermal stability and kinetic parameters were examined using thermogravimetric analysis and differential thermal curves. From dielectric analysis, the electrical conductivity and dielectric behavior of 2C5NA were investigated with variations in frequency and temperature. The organic 2-chloro-5-nitroaniline crystal demonstrates that the indentation size effect is observed in the Vickers micro-hardness test, which was also carried out.

“…Nitriles act as the base compounds for the synthesis of a variety of organic functional materials having triazole, imidazole, or thiadiazole moieties, and nitriles are a proximate neighbor of azoles and hydrazoles [15]. For various industrial applications, nitrile derivatives are used [16]. Compound 4-bromo-2-methylbenzonitrile (4B2MBN) has both the electron acceptor group (methyl-and -CN) group and the electron donator group (bromo-) group.…”

By slowly evaporating 4-bromo-2-methylbenzonitrile at room temperature, it was possible to make a single organic nonlinear optical crystal. The grown crystal's crystalline nature was verified, and the unit cell characteristics are provided as a = 4.08Å, b = 6.61 Å, c = 28.93Å, α = 90º, β = 90º, γ = 90º. The functional groups of the crystal produced were identified using the FTIR and FT-Raman spectra. The UV cutoff wavelength is found at 221.6 nm, and the transparency nature of the crystal was analyzed in the optical studies. The band gap of the grown crystal was estimated using the Taucs’ plot. The violet and red emissions of photoluminescence are discussed. A high dielectric constant was received at a low frequency. The TG/DTA curve shows that the grown crystal was stable up to 125.59 ºC. The Kurtz-Perry powder technique was applied to confirm the Second Harmonic Generation's (SHG) nature. By using the agar diffusion method, the antibacterial property of the grown 4B2MBN crystal was determined.
