Varying the degree of ethylene oxide (EO) functionalization of the zirconium MOF UiO-68 affords two novel MOFs; UiO-68-EO and UiO-68-2EO exhibit solvent-free ionic conductivity upon loading LiTFSI in their pores. Incorporating EO chains provides a pathway for lithium ion migration between the coordinated sites and results in an ionic conductivity of 3.8 x 10-7 S cm-1 and 3.9 x 10-4 S cm-1 at 90 °C for UiO-68-EO/LiTFSI and UiO-68-2EO/LiTFSI resp.

Gao, Xinpei; Mariani, Alessandro; Jeong, Sangsik; Liu, Xu; Dou, Xinwei; Ding, Markus; Moretti, Arianna; Passerini, Stefano published the artcile< Prototype rechargeable magnesium batteries using ionic liquid electrolytes>, Formula: C3H7BrO, the main research area is magnesium ion speciation deposition dissolution process magnesium battery electrolyte; rechargeable magnesium battery ionic liquid electrolyte coordination sphere.

Understanding Mg-ion speciation is of utmost importance to the rational design of electrolytes for rechargeable magnesium batteries. Herein, we report an effort to better understand Mg-ion speciation in ionic liquid (IL) electrolytes through the design of alkoxy-functionalized cations with different alkoxy substituent. In contrast with previous studies focusing on the coordination sphere of Mg2+, the comparison of Raman spectroscopy, electrochem. and DFT calculation results of various IL-based electrolytes suggests that the coordination sphere of transient Mg+ plays a key role in Mg reversible deposition/dissolution process. Finally, a prototype Mg/V2O5 cell using the noncorrosive IL-based electrolyte is demonstrated for the first time, exhibiting a remarkable initial discharge capacity of 140 mAh g-1 and reversible capacity of 100 mAh g-1.

Diez-Castellnou, Marta; Suo, Rongtian; Marro, Nicolas; Matthew, Saphia A. L.; Kay, Euan R. published the artcile< Rapidly Adaptive All-covalent Nanoparticle Surface Engineering>, Application of C3H7BrO, the main research area is gold nanoparticle surface engineering equilibration; acetals; adaptive colloidal nanoparticles; dynamic covalent chemistry; gold nanoparticles; hydrazones.

Emerging nanotechnologies demand the manipulation of nanoscale components with the same predictability and programmability as is taken for granted in mol. synthetic methodologies. Yet installing appropriately reactive chem. functionality on nanomaterial surfaces has previously entailed compromises in terms of reactivity scope, functionalization d., or both. Here, we introduce an idealized dynamic covalent nanoparticle building block for divergent and adaptive post-synthesis modification of colloidal nanomaterials. Acetal-protected monolayer-stabilized gold nanoparticles are prepared via operationally simple protocols and are stable to long-term storage. Tunable surface densities of reactive aldehyde functionalities are revealed on-demand, leading to a wide range of adaptive surface engineering options from one nanoscale synthon. Anal. tractable with mol. precision, interfacial reaction kinetics and dynamic surface constitutions can be probed in situ at the ensemble level. High functionalization densities combined with rapid equilibration kinetics enable environmentally adaptive surface constitutions and rapid nanoparticle property switching in response to simple chem. effectors.

Synthesis of 65 cis- and trans-PCPA derivatives I [R = R1 = H, F; R2 = H, Cl, Me, etc.; R3 = H, F, OH; R4 = H, Br, CF3, etc.] and evaluated their inhibitory activity against LSD1 and LSD2 were reported.

Control of selectivity is one of the central topics in organic chem. Although unprecedented alkoxyl-radical-induced transformations have drawn a lot of attention, compared to selective C-H activation, selective radical O-H activation remains less explored. Herein, we report a novel selective radical O-H activation strategy of diols by combining spatial effects with proton-coupled electron transfer (PCET). It was found that DMSO is an essential reagent that enables the regioselective transformation of diols. Mechanistic studies indicated the existence of the alkoxyl radical and the selective interaction between DMSO and hydroxyl groups. Moreover, the distal C-C cleavage was realized by this selective alkoxyl-radical-initiation protocol.

Ionic liquid is a significant new media and one of the most compelling solvents mentioned in many fields. It is clear that the introduction of ether or allyl group has the advantages of low viscosity and wide application. In this work, [C1OC2pyrr][DCA], [C1OC2pyrr][NTf2] and [Amim][NTf2] were synthesized and characterized. The d., surface tension, and refractive index of the three ionic liquids and their binary systems with acetonitrile were investigated across a complete composition range. The thermal expansion coefficient (αEp), excess molar volumes (VE), and refractive index deviations (ΔnD) are also calculated The αEp and VE are all neg. while the ΔnD are found pos. in the entire concentration range, indicating the presence of strong interactions between ionic liquids and acetonitrile. The properties are fitted to a Redlich-Kister equation and the results have been interpreted in terms of H-bonding interaction and structural effect, at the same time, the corresponding IR spectra are also carried out. The molar refraction and the molar polarizability calculated which suggest that the existent interactions between ionic liquids and acetonitrile are ion-dipole interactions. The molar Gibbs free energy can be measured and explained properly by the improved Eotvos equation. And the molar surface enthalpy also can be gained and is a temperature-independent constant

Song, Tangqiumei; Morales-Collazo, Oscar; Brennecke, Joan F. published the artcile< Solubility and Diffusivity of Oxygen in Ionic Liquids>, Reference of 6482-24-2, the main research area is oxygen solubility diffusivity ionic liquid gravimetry.

The solubility of O2 was measured gravimetrically in 16 ionic liquids (ILs) containing piperidinium, pyrrolidinium, ammonium, tetrahydrothiophenium, methyltriazabicyclodecene, or guanidinium cations paired with bis(trifluoromethanesulfonyl)imide, bis(perfluoroethylsulfonyl)imide, or perfluoropropanoyl(trifluoromethylsulfonyl)imide anions. The temperature dependence of the solubility was determined for eight of the ILs. Henry’ law constants were determined from the solubility data as well as standard enthalpies and entropies of absorption for systems with temperature-dependent data. Knowledge of these thermodn. properties is essential in guiding the structural design of ionic liquids for different applications involving O2. The O2 solubility did not follow any obvious trend with regard to IL structure or molar volume; instead, the dipole-quadrupole interactions are the primary driving forces for O2 dissolution in ionic liquids, as demonstrated by neg. standard enthalpies of absorption for all of the ILs. In addition, diffusion coefficients of O2 in the ILs as a function of temperature (293, 313, and 333 K) and applied O2 pressure (1, 3, and 5 MPa) were obtained by fitting the time-dependent absorption data to a widely used mass diffusion model. The diffusion coefficients of O2 in ionic liquids at 293 K and 1 MPa roughly correlate inversely with the pure IL viscosity, likely due to the relatively low and similar O2 solubilities under these conditions. As expected, O2 diffusivities increase with increasing temperature However, they also increase with increasing pressure, likely due to decreasing solution viscosity with increasing gas solubility
