“…Figure 13 demonstrates the recorded hysteresis loops (M-H curves) of ligand and Cu (II) Complex under a range of 15 kOe magnetic field at room temperature. As can be observed, the synthesized Cu (II) Complex sample indicates a dominant paramagnetic phase that is not magnetically saturated even at 14 kOe applied field, which could be attributed to the paramagnetic nature of the Cu(II) 64 . Also, it has a weak ferromagnetism phase, and its extracted data were summarized in Table 5 .…”

A new series of Cu (II) complexes were prepared using Schiff base ligand of N–N′-(1,2-diphenyl ethane-1,2-diylidene)bis(3-Nitrobenzohydrazide). The prepared ligand and Cu (II) complex were characterized using various physicochemical investigations such as X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), and Energy dispersive X-ray analysis (EDX), Fourier Transform Infrared (FT-IR), $${}^{13}C$$ 13 C Nuclear Magnetic Resonance (NMR), $${}^{1}H$$ 1 H NMR, Diffuse Reflectance Spectroscopy (DRS), Vibrating Sample Magnetometer (VSM), and Z-Scan technique (Nonlinear optical (NLO) properties). In addition, the prepared samples have been examined for their NLO characteristics with the help of the Density Functional Theory calculations which proved that the Cu (II) Complex is more polarized than Ligand. According to XRD and FESEM results, the nanocrystalline nature of the samples is confirmed. The metal-oxide bond assigned in the functional studies by FTIR. Magnetic studies demonstrate weak ferromagnetic and paramagnetic nature for Cu (II) complex and diamagnetic nature for the ligand, respectively. DRS spectrum exhibited higher reflectance for Cu (II) than the ligand. The band gap energies of the synthesized samples were estimated by employing the Tauc relation and Kubelka–Munk theory on reflectance data and found to be 2.89 eV and 2.67 eV for Cu (II) complex and ligand, respectively. Extinction coefficient and refractive index values were calculated using the Kramers–Kronig method. The z-scan technique was applied to estimate the NLO properties by a 532 nm Nd:YAG laser.

Second order nonlinear optical properties of Cu(dppb)(pz 2 Bph 2 ), where dppb = 1,2-bis(diphenylphosphino)benzene and pz 2 Bph 2 = diphenyl-bis(pyrazol-1-yl)borate were investigated. In particular, optical second harmonic was generated with different polymer films containing dc-electric field aligned chromophore molecules. It was shown that in such dc-electric field aligned polymer films, the enhancement of the second order output efficiency may be up to 3 times higher with as compared to the non-aligned poly(methylmethacrylate) (PMMA). After switching off the external dc-electric field the second order susceptibility decreases within 5-7 min by about 40 % with respect to the photoinduced ones. After that time, the second harmonic generation efficiency remains constant for much more than a few hours.

“…Due to the excellent stability, selectivity, and sensitivity of Schiff bases, they are used in modern technology, they are used in optical computers, to measure and control the intensity of radiation, in imaging systems, in molecular memory storage, as organic materials in the reversible optical memories and photo detectors in biological systems. This is why they are still in use in a variety of researches [60][61][62][63].…”

Two Schiff base compounds viz., Ethyl (E)-4-((3-ethoxy-2-hydroxybenzylidene)amino)benzoate(EHB) and Ethyl (E)-4-(((2-hydroxynaphthalen-1-yl)methylene)amino)benzoate(ENB) are synthesized by condensation of ethyl-4-amino benzoate with 2-hydroxy-3-ethoxy benzaldehyde and 2-hydroxy-1-naphthaldehyde. The two compounds are studied and identified by FT-IR, UV-visible, Mass, 1H-NMR and 13C-NMR spectroscopies. The nonlinear refractive index (NRI) of the two compounds are determined, for ENB compound via the diffraction ring patterns (DRPs) and the Z-scan and via Z-scan for the EHB compound, using continuous wave (cw) low power laser beam, and founds of the order of 10-7 cm2/W due to the first technique and 10-8 cm2/W due to the second technique. The optical limiting (OLg) property of both compounds is studied too with OLg thresholds of 16.5 mW and 11 mW for the compounds EHB and ENB respectively, which makes these two compounds as candidates to be used as an optical limiter (OLr). The DRPs are numerically simulated based on the theory of Fresnel-Kirchhoff with reasonable agreement compare to the experimental findings.
