Flexible nanoporous chromium or iron terephtalates (BDC) MIL-53(Cr, Fe) M(OH)[BDC] have been used as matrices for the adsorption and in vitro drug delivery of Ibuprofen (or α-p-isobutylphenylpropionic acid). Both MIL-53(Cr) MIL-53(Fe) solids adsorb around 20 wt % (Ibuprofen/dehydrated MIL-53 molar ratio = 0.22(1)), indicating that amount inserted does not depend on metal (Cr, constitutive hybrid framework. Structural spectroscopic characterizations are provided solid filled with Ibuprofen....
Titanium is a very attractive candidate for MOFs due to its low toxicity, redox activity, and photocatalytic properties. We present here MIL-125, the first example of highly porous crystalline titanium(IV) dicarboxylate (MIL stands Materials Institut Lavoisier) with high thermal stability photochemical Its structure built up from pseudo cubic arrangement octameric wheels, edge- or corner-sharing titanium octahedra, terephthalate dianions leading three-dimensional periodic array two types...
The unusual adsorption behavior of CO2 in a nanoporous hybrid metal– organic solid is discussed (see figure). results indicate that the gas adsorption–desorption step related to breathing phenomenon. This study also suggests main interactions responsible for phenomenon are strong guest–framework CO2–OH as well CO2–CO2 along tunnels present structure.

The synthesis on the gram scale and characterization of a series flexible functionalized iron terephthalate MIL-53(Fe) type solids are reported. Chemical groups various polarities, hydrophilicities, acidities (-Cl, -Br, -CF(3), -CH(3), -NH(2), -OH, -CO(2)H) were introduced through aromatic linker, to systematically modify pore surface. X-ray powder diffraction (XRPD), molecular simulations, thermogravimetric analyses, in situ IR (57)Fe Mössbauer spectrometries indicate some similarities with...
A joint experimental and computational systematic exploration of the driving forces that govern (i) encapsulation active ingredients (solvent, starting material dehydration, drug/material ratio, immersion time, several consecutive impregnations) its kinetics delivery (structure, polarity, ...) was performed using a series porous biocompatible metal–organic frameworks (MOFs) bear different topologies, connectivities, chemical compositions. The liporeductor cosmetic caffeine selected as...
Brolly good MOFs: A new series of hydrophobic isoreticular porous Zr oxide dicarboxylate MOFs have been prepared (see picture, blue polyhedra, O red, C black). They a one-dimensional pore system, rare combination Lewis acidity and character, higher hydrothermal mechanical stability than their UiO MOF polymorph counterparts.
A series of organically modified iron(III) terephthalate MIL-88B and 4,4′-biphenyl dicarboxylate MIL-88D flexible solids have been synthesized characterized through a combination X-ray diffraction, IR spectroscopy, thermal analysis (MIL stands for Material from Institut Lavoisier). The swelling amplitude the highly MOFs tuned by introducing functional groups onto phenyl rings shows clear dependence on steric hindrance number per aromatic ring. For instance, while introduction four methyl...
The present study attempts to understand the use of flexible porous chromium terephthalate Cr(OH)(O2C−C6H4−CO2) denoted MIL-53(Cr) (MIL = Material from Institut Lavoisier) for separation mixtures CO2 and CH4 at ambient temperature. coadsorption was studied by a variety different techniques. In situ synchrotron X-ray Powder Diffraction allowed breathing solid upon adsorption gas simultaneously measured Raman spectra yielded an estimation adsorbed quantities CH4, as well quantification...
Abstract Conventional SO 2 scrubbing agents, namely calcium oxide and zeolites, are often used to remove using a strong or irreversible adsorption-based process. However, adsorbents capable of sensing selectively capturing this toxic molecule in reversible manner, with in-depth understanding structure–property relationships, have been rarely explored. Here we report the selective removal recently unveiled fluorinated metal–organic frameworks (MOFs). Mixed gas adsorption experiments were...
The ligand functionalization effect on the CO2/CH4 separation performance of MOF type UiO-66(Zr) was explored computationally. –SO3H and –CO2H functionalized forms show highest selectivity, good working capacity medium ranged CO2 adsorption enthalpy that make these materials very promising for physisorption-based processes.
Natural gas must be dehydrated before it can transported and used, but conventional drying agents such as activated alumina or inorganic molecular sieves require an energy-intensive desiccant-regeneration step. We report a hydrolytically stable fluorinated metal-organic framework, AlFFIVE-1-Ni (KAUST-8), with periodic array of open metal coordination sites fluorine moieties within the contracted square-shaped one-dimensional channel. This material selectively removed water vapor from streams...
One flue over the cuckoo's nest: A novel porous Zr-based MOF combining a high chemical stability, easy “green” synthesis and scalability is prepared. This material incorporating carboxylic functions on its organic linkers has thermodynamically kinetically very promising properties for CO2 capture from post-combustion gas under real working conditions.

This approach allows "breathing" of in presence CO2 to be captured gives insight into structural switching mechanism from a narrow- large-pore form (see picture). can used directly studies many guest molecules and, with minimum adjustment, other MOF systems.
A new hydrothermally stable Al polycarboxylate metal–organic framework (MOF) based on a heteroatom bio-derived aromatic spacer is designed through template-free green synthesis process. It appears that in some test conditions this MOF outperforms the heat reallocation performances of commercial SAPO-34.
