“…Among them, the z-scan technique [15,16] has a great advantage, because of its simplicity and high sensitivity by which one can simultaneously characterize the nonlinear optical absorption and the refraction of the nonlinear optical materials. Despite, a number of organometallic complexes have been studied [17][18][19][20][21][22], using z-scan technique, but the investigations of such materials are still unexploited. Very recently, nonlinear optical investigation of 1,1'-methylenedipyridinium tetrachloridecuprate(II)] was reported by us [23].…”

The third-order nonlinear optical properties of 1,1'-methylenedipyridinium bis[tetrachloride gold(III)] were investigated by the z-scan method using CW diode laser. The experimental results led to estimation of the nonlinear optical absorption coefficient (β), the nonlinear optical refraction (n2), and third-order nonlinear optical susceptibility (χ 3 ). Our results show that the excited-state absorption cross-sections (σex) is larger than the groundstate absorption cross-sections (σg), this suggests that the nonlinear optical absorption in the MPTC gold(III) is due to the reverse saturable absorption mechanism. Furthermore, the obtained results suggest that our material is considered as a promising candidate for future optical devices applications.

“…It can be seen that 1, 1 -methylenedipyridinium pentacynidonitrosoferrate(II)pentahydrate shows large thirdorder nonlinear optical properties because of the delocalized electronic states formed by the overlapping between π → π * and d orbitals [19,44,45]. The experiments were repeated for the pure solvent to account for its contribution, but no significant measurable signals were produced in either the opened or the closed Z-scan traces.…”

The organic-inorganic hybrid salt: 1, 1 -methylenedipyridinium pentacynidonitrosoferrate(II)pentahydrate is synthesized and characterized by multinuclear NMR, IR, and UV-vis spectroscopies and elemental analysis. The third order nonlinear optical properties of the new complex in an aqueous solution have been studied using Z-scan technique. Measurements were performed for input intensities (I0) of 437 and 241 W/cm 2 for the two concentrations with a CW diode laser at 635 nm wavelength. The nonlinear optical absorption coefficient (β) and nonlinear refraction (n2) are found at 1.28 × 10 −3 cm/W and 10.17 × 10 −9 cm 2 /W, respectively. The overall results suggested that better nonlinearity was observed at a higher concentration of sample. Our results suggest that this material is considered as a promising candidate for future optical device applications.

In this research, a novel organic-inorganic hybrid salt, namely, N 1 ,N 1 ,N 2 ,N 2-tetramethyl-N 1 ,N 2-bis(sulfo)ethane-1,2-diaminium tetrachloroferrate ([TMBSED] [FeCl 4 ] 2) was prepared and characterized by Fourier-transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDX), elemental mapping, field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), thermal gravimetric (TG), differential thermal gravimetric (DTG), and vibrating-sample magnetometry (VSM) analyses. Catalytic activity of the hybrid salt was tested for the synthesis of N,N 0-alkylidene bisamides through the reaction of benzamide (2 eq.) and aromatic aldehydes (1 eq.) under solvent-free conditions in which the products were obtained in high yields and short reaction times. The catalyst was superior to many of the reported catalysts in terms of two or more of these factors: the reaction medium and temperature, yield, time, and turnover frequency (TOF). [TMBSED][FeCl 4 ] 2 is a Brønsted-Lewis acidic catalyst; there are two SO 3 H groups (as Brønsted acidic sites) and two tetrachloroferrate anions (as Lewis acidic sites) in its structure. Highly effectiveness of the catalyst for the synthesis of N,N 0-alkylidene bisamides can be attributed to synergy of the Brønsted and Lewis acids and also possessing two sites of each acid.
