“…Organic NLO compounds are preferably used because of structural diversity, polarity and extensive conjugation. 76 The electronic properties of the material are correlated to the average linear polarizability 〈 α 〉, first hyperpolarizability ( β tot ) and second hyperpolarizability ( γ tot ) responses and are also responsible for optical activity. Moreover, these NLO properties can be improved by using various π-bridge and acceptor moieties.…”

“… 5 Organic NLO compounds are preferred over other NLO molecules due to their extended π-electrons framework and versatile formulation. 6 NLO properties depend on intramolecular charge transfer (ICT) which is the fundamental process. In the organic compounds, the ICT system can be implied through donor–π–acceptor arrangement with excellent polarization, showing substantial NLO properties.…”

Bulk organic nonlinear optical (NLO) single crystals of DEBM (2-[4-(diethylamino)benzylidene]malononitrile), with sizes up to 22 × 5 × 12 mm 3 have been grown in ethyl acetate solution by the slow evaporation method. The lattice parameters and crystalline purity of the titled crystal were measured by single crystal X-ray diffraction and powder XRD, respectively. The morphology of the grown crystal was portrayed by WinXMorph program. Fourier transform infrared (FT-IR) spectral studies have been performed to identify the functional groups. The molecular structure was confirmed through 1 H NMR. UV−vis−NIR spectral analysis signifies that the DEBM crystal is transparent in entire visible and near-infrared region, which has a lower cutoff wavelength around 476.8 nm. The optical band gap (E g ) was estimated from the Tauc plot and was found to be about 2.68 eV. The low value of the dielectric constant (ε r ) of DEBM suggests that it has a possible strategy toward the microelectronics industry. Thermal stability and melting point (137.8 °C) were studied with TGA−DSC analysis. The laserinduced damage threshold (LDT) experiments showed that the grown DEBM bulk crystal possess an excellent resistance to laser radiation with a high threshold up to 1.95 GW cm −2 , it is still better compared to other organic and inorganic NLO materials. The third-order optical nonlinearities of the DEBM crystal was confirmed by the single beam Z-scan technique. All these results demonstrate that the organic crystal DEBM is promising for NLO applications.

An efficient semi-organic nonlinear optical bis (4-acetylanilinium) tetrachloridozincate [(C8H10NO)2 ZnCl4] (B4ATCZ) single crystal was synthesized and successfully grown by the slow evaporation method. The single-crystal X-ray diffraction data confirm that B4ATCZ crystallized into an orthorhombic crystal system (Cmca). The UV–Vis–NIR transmittance spectrum was taken to assess the optical transmission, cut-off wavelength, and bandgap energy. The TG–DSC investigation ensures that the B4ATCZ is stable up to 235 °C. The mechanical behavior of the B4ATCZ compound was determined by Vickers Microhardness analysis. The surface laser-induced damage threshold value of the grown B4ATCZ crystal was endowed to be 19.78 GW/cm2 on testing with 1064 nm Nd: YAG laser radiation. The positive photoconductive properties and charge transport mechanism of B4ATCZ crystal were analyzed through photoconductivity and dielectric studies. The electron excitation and lifetime measurements of the molecules in the B4ATCZ crystal were studied by fluorescence spectral analysis. The HOMO–LUMO analysis evidently interprets the occurrence of N–H⋯O and N–H⋯Cl intermolecular hydrogen bonds influencing the charge transfer in the system. The electrostatic potential surface reveals the possible sites for hydrogen bonding electrophilic and nucleophilic interactions. Third-order nonlinear optical activity evaluated by the Z-scan measurements indicates the self-focusing and reverse saturable absorption in the crystal. The aforesaid results affirm that the metal-organic B4ATCZ is a potential material for optoelectronic and nonlinear optical device applications.
