Adsorption of Fluorocarbons and Chlorocarbons by Highly Porous and Robust Fluorinated Zirconium Metal-Organic Frameworks

Fluorocarbons and chlorocarbons are common volatile organic compounds that pose serious risk to the environment and human health and therefore need to be effectively captured. Herein, we report a series of highly fluorinated metal-organic frameworks with high porosity (Brunauer-Emmett-Teller surface area 3000 m2/g) and stability. They show exceptionally high capacity and good recyclability toward the adsorption of fluorocarbons and chlorocarbons.

A new polymer with low dielectric constant based on trifluoromethyl-substituted arene: Preparation and properties

A new polymer with low dielectric constant is reported here. This polymer contains a trifluoromethyl-substituted phenyl unit and a binaphthyl unit, and shows high thermostability with a glass transition temperature of 244 °C and a 5 wt% loss at temperature 518 °C under nitrogen. The polymer also exhibits good film-forming ability, and the formed films exhibit high hydrophobicity with a contact angle of 103.6° with water. In a range of frequencies from 1 to 25 MHz, the polymer reveals an average dielectric constants of about 2.56. In regard to the mechanical properties, the polymer film shows an average hardness of 0.37 GPa and a Young's modulus of 15.07 GPa. These results indicate that the polymer could be used as a varnish for enameled wire, sizing agents for high-performance carbon fiber, and the matrix resin for the production of laminated composites utilized in the printed-circuit-board (PCB) industry.

Functionalization in flexible porous solids: Effects on the pore opening and the host-guest interactions

The synthesis on the gram scale and characterization of a series of flexible functionalized iron terephthalate MIL-53(Fe) type solids are reported. Chemical groups of various polarities, hydrophilicities, and acidities (-Cl, -Br, -CF3, -CH3, -NH2, -OH, -CO2H) were introduced through the aromatic linker, to systematically modify the pore surface. X-ray powder diffraction (XRPD), molecular simulations, thermogravimetric analyses, and in situ IR and 57Fe Moessbauer spectrometries indicate some similarities with the pristine MIL-53(Fe) solid, with the adoption of the narrow pore form for all solids in both the hydrated and dry forms. Combined XRPD and computational structure determinations allow concluding that the geometry of the pore opening is predominantly correlated with the intraframework interactions rather than the steric hindrance of the substituent. Only (MIL-53(Fe)-(CF3)2) exhibits a nitrogen accessible porosity (SBET ≈ 100 m2 g-1). The adsorption of some liquids leads to pore openings showing some very specific behaviors depending on the guest-MIL-53(Fe) framework interactions, which can be related to the energy difference between the narrow and large pore forms evaluated by molecular simulation.
