A new metal−organic framework (MOF), [Zn 4 (μ 4 -O)(μ 6 -L) 2 (H 2 O) 2 ] n • nDMF (ZSTU-10), was assembled from zinc(II) nitrate and N,N′,N″-bis(4carboxylate)trimesicamide linkers and fully characterized. Its crystal structure discloses an intricate two-fold 3D+3D interpenetrated MOF driven by the [Zn 4 (μ 4 -O)]-based tetragonal secondary building units and the C3-symmetric tris-amide-tricarboxylate linkers (μ 6 -L 3− ). Topological analysis of ZSTU-10 reveals two interpenetrated 3,6connected nets with an rtl (rutile) topology. Z-Scan analysis at 532 nm was conducted to study a nonlinear optical (NLO) behavior of ZSTU-10. The nonlinear responses of ZSTU-10 were explored under various laser intensities, revealing notable third-order NLO properties in the visible region. A large two-photon absorption at lower incident intensities highlights the fact that ZSTU-10 can be applied in optical limiting devices as well as optical modulators. Moreover, a nonlinear refractive index (n 2 ) is indicative of a self-defocusing behavior. This work thus expands a family of novel MOF materials with remarkable optical properties.

“…A typical Z-scan setup is described well. 62 This technique involves a z-direction scanning of the samples using various laser intensities. The nonlinear optical materials exhibit a dip or a peak upon undergoing a transition over z = 0 (lens focal point), which is attributed to TPA (two-photon absorption) or SA (saturable absorption).…”

The nitrogen-doped carbon nano-onions (NCNOs) were prepared by annealing the ultra-dispersed aminated-nanodiamond solution under He gas at 1150°C followed by calcination at 400°C. The nanostructures of CoWO4, MnO2, CoWO4-MnO2, and CoWO4-MnO2-NCNO were synthesized through the simple precipitation method under ultrasonication followed by calcination at 450°C. The morphology, structure, and optoelectronic properties of the samples were examined by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and Z-scan method. The homogeneous distribution of the tiny aggregated plate-like and spongy particles throughout the nanocomposite created a highly porous nanostructure with a large surface area. The nonlinear absorption (NLA) coefficient and nonlinear refractive (NLR) index were of the order of 10-3(cm/W) and 10-8(cm2/W), respectively. In different incident intensity of laser, all synthesized samples show TPA effect implying the positive sign of NLA coefficient. MnO2 and NCNO structure have positive NLR index indicating the self-focusing optical nonlinearity. The self-defocusing effect and the negative sign of nonlinearity in the CoWO4 nanoparticles, MnO2-CoWO4, and MnO2-NCNO-CoWO4 nanocomposites are vivid. The porous structure of CoWO4 nanoparticles and trapping the light into CoWO4 nanoparticles are the main reasons for nonlinearity of this nanoparticles. Porosity is also one of the most important reasons for the nonlinear optical responses of NCNO structure. The NLR index and NLA coefficient of MnO2 decreased by increasing the incident intensity. Moreover, an increase in the incident intensity improved the nonlinear responses in the rest of samples. The present nonlinear optical results of the synthesized samples can be applied in optical devices.

Two Curcumin (Cur) based mixed ligand complexes of Nickel have been investigated for their optical nonlinearity (NLO). Physicochemical characterization of two nickel precursors and their interaction with curcumin produced two molecules, namely Ni(C3S5)(Cur).2H2O (abbreviated as NiThCur) and NiCl(Cur)(PPh3) (abbreviated as NiTppCur). Additionally the Conceptual‐Density‐Functional‐Theory (CDFT) studies were performed. CDFT‐based optimization parameters of both molecules are theoretically interpreted. HOMO‐LUMO energy gap of NiThCur and NiTppCur were calculated 1.474 eV and 2.744 eV respectively. Both molecules demonstrated good NLO activities, studied by a Z‐scan approach and additionally with a Differential Four wave Mixing (DFWM) technique. Preliminarily investigations showed that the molecules can be potential optical limiters (OL). These studies divulge the exhibition of a 3‐photon absorption (3PA) mechanism by the synthesized molecules. NLO absorption 3PA coefficient (γ) value of 1.34×10−24 m3/W2, third‐order optical susceptibility (χ(3)) value of 1.543×10−11 esu, and the figure of merit 6.64×10−14 esu was observed for the NiThCur complex and γ=3.61×10−24 m3/W2, χ(3)=1.521×10−11 esu, and FoM=5.61×10−14 esu for NiTppCur with Z‐scan (γ and χ(3)) and DFWM methods, respectively. Normalized transmittance (NT) exhibited a decrease to 78.5 % from 100 % in NiThCur and to 69.5 % in NiTppCur. Optical limiting calculations are also presented.
