“…Figure b shows the surface of the FNNDPB crystal before etching, no defined pattern was observed. The rectangular etch pits were observed with 5–20 s. The rectangular etch pits got elongated when etch time increased, this may be due to the presence of dislocation caused by thermal stress which is imposed on the growth surface …”

Nonlinear optical organic materials of N,N-diphenylbenzamide (NNDPB) and 4-fluoro-N,N-diphenylbenzamide (FNNDPB) are synthesized from benzoylation of N,N-diphenylamine using the substituted benzoyl chlorides. The single crystals of NNDPB and FNNDPB are grown by a slow evaporation technique. Single-crystal X-ray diffraction shows that both the crystals belong to orthorhombic crystallographic system with space group Pbca. Fourier transform infrared spectrum shows the chemical bonding and various functional groups, the carbonyl peak appeared at 1647 and 1651 cm −1 in NNDPB and FNNDPB compounds, respectively. 1 H and 13 C nuclear magnetic resonance analysis examines the placement of aromatic protons and carbons are identified to the synthesized materials. UV-vis near IR spectra analysis showed 100% transmission in the visible region for both NNDPB and FNNDPB crystals. As-grown crystal dielectric constant and dielectric loss are inversely proportional to the frequency at all the temperatures. The thermal properties of NNDPB and FNNDPB crystals are studied from thermogravimetric analysis/differential thermal analysis analysis, it is thermally stable up to 483 and 503 K. Crystal growth mechanism and defects are observed from etching studies. The relative second harmonic generation efficiency is measured by Kurtz-Perry powder technique and is found to be 1.55 and 1.7 times as that of potassium dihydrogen phosphate.

“…Due to their potential applications in communication, electro-optical modulation, photo refractivity, optical storage, harmonic generation, terahertz wave generation and detection, optical switching, signal processing, and laser remote sensing, organic charge transfer, Nonlinear Optical (NLO) materials have played a significant role in the development of photonics in recent years [1] [2] [3]. Organic molecules provide increased nonlinear optical characteristics in cost-effective way due to their molecular flexibility [4].…”

An organic nonlinear optical material 2-Amino-4-methylpyridinium 2-chloro 4-nitro benzoate (AMPCNB) was synthesized and large size single crystals were grown by slow evaporation solution growth method. Single crystal X-ray diffraction study showed that the title compound belongs to monoclinic crystal system with P2 1 /n space group. A powder XRD study was performed to ascertain its phase. The UV-VIS-NIR study was performed to investigate the transparency window and lower cutoff wavelength of the compound, no absorption has been observed between 318 and 1100 nm. The third harmonic efficiency of the title compound has been studied using the Z-scan technique using continuous-wave Nd:YAG laser to confirm its saturable absorption and self-defocusing effect. The photo conducting and charge transport properties are analyzed using photoconductivity and dielectric measurements. Theoretical calculation of molecular polarizability, which is helpful in device fabrication, was carried out from Penn gap, Clausius-Mosotti equations and the obtained results were compared. Mechanical properties of the grown crystal were investigated by Vicker's microhardness study.

“…However, in crystal growth organic crystals have relatively weak intermolecular bindings and it is too difficult to grow high quality large size crystals compared with inorganic crystals. 4-Aminobenzoic acid (4-ABA) is one of the well known carboxylic acids to promoting molecular self assembly by means of strong hydrogen bonding through its carboxylic acid group and the ring substituted amino group of 4-nitroanilne (4-NA) [6][7][8][9][10]. Strong hydrogen bonds occur due to the polarizable hydrogen atom covalently bonded to an electron-withdrawing donor nitrogen atom and interact with a partially negatively charged and comparatively less polarizable acceptor oxygen atom, which will also increase the molecular hyperpolarizability [11].…”
