“…Poled organic thin films are technologically useful materials [1][2][3][4][5][6][7][8][9] which have several advantages over traditional inorganic crystals including ease of processing [10], larger second order susceptibilities [11], an intrinsically low dielectric constant [10], and significantly faster responses [12][13][14][15]. Our approach to poled organic films involves surfaceinduced polar alignment of main chain noncentrosymmetric hydrogen bonded liquid crystalline macromolecules [16].…”

The syntheses and characterization of three noncentrosymmetric main chain hydrogen bonded macromolecules which incorporate aniline, alkanoic acid, and alkanol hydrogen bond donor units are reported. These macromolecules participate in weak intermolecular hydrogen bonding as demonstrated using attenuated total reflectance (ATR) FTIR. The phase transitions of these macromolecules depend on the identity of the hydrogen bond donor.

“…The organic crystals are being recently a source of interest as terahertz (THz) emitters as they have been reported to generate stronger THz signals than commonly used semiconductors or inorganic emitters [1][2][3][4]. Much effort has been made to develop new materials with high second-order nonlinearities which are expected to support applications in the areas such as electro-optic switching for telecommunications [5], optical information processing [6], optical data storage [7,8] and the generation of terahertz radiation [9].…”

Metathesis ionic exchange reaction process was used to synthesize a novel nonlinear optical material: 4-N,N-dimethylamino-4 -N -methylstilbazolium 2,4-dimethylbenzenesulfonate (DSDMS). The growth of DSDMS single crystals was carried out by adopting the solution growth technique. The crystal perfection and lattice parameters were elucidated from single XRD and powder XRD, respectively and its morphology was interpreted by WinXMorph program. FT-IR and Raman spectral analyses confirmed the existence of functional groups and their corresponding vibrational modes. UV-Vis spectral studies revealed the optical transmission region. Mechanical stability of the crystal was determined from Vickers microhardness number H v , Meyer's index n and elastic stiffness constant C 11 . Dielectric and thermal behavior of the grown crystal were elucidated by using impedance analyser and thermogravimetric analysis.

“…In recent years, organic materials have attracted many researchers due to its high nonlinearities, ultrafast response in electrooptic effect, large optical susceptibilities, large second order molecular polarizability, and higher resistance to optical damage and they have wide applications in optical communications, frequency mixing, optical parametric oscillation, information storage, and so forth [1][2][3][4]. According to crystal engineering, second harmonic generation occurs mostly in noncentrosymmetric crystals due to nonzero hyperpolarizability.…”

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.
