“…The observed diffraction pattern is shown in Figure 2 and cell parameters of IMLT crystals were identified and given in Table 1. The unit cell parameters are found in very good agreement with previously reported values [11,13]. The crystallite size has been obtained by Scherrer equation, L = K /W cos , where k = 0.94, = 1.54178Å, and W is full width at half-maxima.…”

“…Hence it is potentially adept to form 1:1 and 1:2 proton transfer salts with most of Lewis bases [8], although it is possible to form 1:1 hydrogen tartrate salts using stoichiometric control and large number of them have been studied [9]. The ferroelectricity study of bis(imidazolium) L-Tartrate [10], structural, thermal expansion, laser damage threshold (LDT) and SHG efficiency [11], growth with SR method along with dielectric study [12], and quantum mechanical calculation using DFT [13] of imidazolium L-Tartrate has been reported. In the present work an organic NLO crystal of imidazolium L-Tartrate (IMLT) has been grown and characterized by Powder XRD, FTIR, UV-Vis spectroscopy, Thermogravimetry, and linear optical and SHG studies.…”

Good quality single crystals of organic imidazolium L-Tartrate (IMLT) are grown up from aqueous solution by slow solvent evaporation technique. Various structural parameters and monoclinic crystal structure have been confirmed using powder X-ray diffraction method. The presence of various functional groups has been identified by ATR-FTIR. UV-Vis-NIR spectroscopy has shown more than 60% of optical transparency with the lower UV cutoff at 245nm. The optical band gap value of the material is evaluated to be 4.8 eV. Other optical parameters such as refractive index, optical and electrical conductivity, Urbach energy, extinction coefficient, and optical and electrical susceptibility have been evaluated from transmission spectrum data. The above essential parameters manifest appropriate usage of IMLT as an NLO material. The thermogravimetric analysis indicates high thermal stability of material up to 214°C. Apart from that, the dielectric study at various temperatures confirms decrement of dielectric constant and dielectric loss at higher frequencies. The efficiency of Second Harmonic Generation (SHG) is found to be 3.5 times that of the KDP crystals. A range of analysis suggests suitability and potentiality of IMLT crystal for various optoelectronic applications.

“…Meanwhile, the Raman spectrum of multishelled Fe 2 (MoO 4 ) 3 hollow spheres confirms that there is no MoO 3 (Figure 3i and Figure S11). 39 The inductively coupled plasma mass spectrometry MS (ICP-MS) test shown in Table S6 demonstrates that the molar ratio of Mo/Fe is around 1.5. Finally, from the element mapping (Figure 3e) by high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) of quintuple-shelled Fe 2 (MoO 4 ) 3 hollow spheres treated by microtomy and X-ray photoelectron spectroscopy (XPS, shown in Figure 3g and h), it can be seen clearly that the Fe 3+ and Mo 6+ are distributed uniformly in quintuple-shelled Fe 2 (MoO 4 ) 3 hollow spheres.…”

Multishelled binary metal oxide, which can exert a synergetic effect of different oxides, is a promising electrochemical electrode material. However, it is challenging to synthesize this kind of binary metal oxide due to the severe hydrolysis and/or precipitation reactions of the precursors between cations and anions of different metals. Herein, by using citric acid as a chelating agent to inhibit hydrolysis and precipitation, a series of multishelled binary metal oxide hollow spheres (Fe 2 (MoO 4 ) 3 , NiMoO 4 , MnMoO 4 , CoWO 4 , MnWO 4 , etc.) were obtained via coabsorption of negative and positive metal ions. In addition, the chelation between a metal ion and citric acid is systematically validated by NMR, MS, Raman, and UV−vis. In particular, multishelled Fe 2 (MoO 4 ) 3 hollow spheres show excellent electrochemical performance as cathode material for sodium-ion batteries benefited from their structural superiorities. Especially, the quintuple-shelled Fe 2 (MoO 4 ) 3 hollow sphere shows the highest specific capacity (99.03 mAh g −1 ) among all Fe 2 (MoO 4 ) 3 hollow spheres, excellent stability (85.6 mAh g −1 was retained after 100 cycles at a current density of 2.2 C), and outstanding rate capability (67.4 mAh g −1 can be obtained at a current density of 10 C). This general approach can be extended to the synthesis of other multishelled multielement metal oxides and greatly enrich the diversity of hollow multishelled structures.

“…Probe 1 was simply synthesized from commercially available 4‐bromo‐1,8‐naphthalic anhydride in four steps and the synthesis pathway was displayed in Scheme 2. Briefly, the 4‐bromo‐1,8‐naphthalic anhydride was condensed with hydrazine to prepare Compound 3 , 16 which reacted with 4‐(diethylamino)salicylaldehyde using a catalytic amount of AcOH in EtOH to afford Compound 2 . Then, the 2 was subjected to a nucleophilic substitution reaction by NaN 3 in DMF to give Probe 1 .…”

Hydrogen sulfide (H2S) acts as a crucial biological and environmental component in a variety of processes. Abnormal levels of H2S endogenously generated in human body are associated with various diseases. Meanwhile, H2S gas leaked from various manufacturing environments has a fatal effect against the human body. For this reason, H2S has been considered as a potential biomarker for the diagnosis and treatment of various human diseases, and as a toxic gas that should be detected when leaked to the workplace for the safety of workers. In this study, we synthesized an azide‐containing naphthalimide derivative that can play as a fluorescence turn‐on probe for H2S.
