Gas Adsorption in R2-MOF-5 Difunctionalized with Alkyl Groups

Zinc terephthalate metal?organic framework (MOF) MOF-5 and some of its dialkylated derivatives (R2-MOF-5; R=Me, Et, Pr, Bu) were obtained from a solvothermal synthesis using 2,5-dialkyl-1,4-benzenedicarboxylic acids with zinc nitrite. The effect of the solvent on the solvothermal synthesis of R2-MOF-5 was investigated. For R=H and Me, interpenetrating or non-interpenetrating MOFs obtained depending on the choice of reaction solvent, while for R=Et, Pr, and Bu, no such solvent effect was observed, and only jungle-gym-type MOFs were generated. All compounds were fully characterized using powder X-ray diffraction analysis (PXRD), Fourier-transform infrared (FT-IR) spectroscopy, and thermogravimetric analysis (TGA). After activation, all these compounds exhibit significant porosity, as confirmed by N2-, H2-, and CO2-sorption experiments. The N2-adsorption capacity of these compounds depends on the size of the attached alkyl groups, while the H2-uptake values tend to increase for the alkyl-functionalized MOFs relative to the unfunctionalized parent MOFs and exhibit a maximum value for Pr2-MOF-5.

Isoreticular Crystallization of Highly Porous Cubic Covalent Organic Cage Compounds**

Modular frameworks featuring well-defined pore structures in microscale domains establish tailor-made porous materials. For open molecular solids however, maintaining long-range order after desolvation is inherently challenging, since packing is usually governed by only a few supramolecular interactions. Here we report on two series of nanocubes obtained by co-condensation of two different hexahydroxy tribenzotriquinacenes (TBTQs) and benzene-1,4-diboronic acids (BDBAs) with varying linear alkyl chains in 2,5-position. n-Butyl groups at the apical position of the TBTQ vertices yielded soluble model compounds, which were analyzed by mass spectrometry and NMR spectroscopy. In contrast, methyl-substituted cages spontaneously crystallized as isostructural and highly porous solids with BET surface areas and pore volumes of up to 3426 m2 g?1 and 1.84 cm3 g?1. Single crystal X-ray diffraction and sorption measurements revealed an intricate cubic arrangement of alternating micro- and mesopores in the range of 0.97–2.2 nm that are fine-tuned by the alkyl substituents at the BDBA linker.

Functionalization of Zr-based MOFs with alkyl and perfluoroalkyl groups: the effect on the water sorption behavior

Stability and sorption of Metal-Organic Frameworks (MOFs) towards water are critical in many applications, and can a priori be modulated through the introduction of suitable organic functional groups on their backbone. We report here the preparation of a

Cyclic [2]pseudorotaxane tetramers consisting of two rigid rods threaded through two bis-macrocycles: Copper(I)-templated synthesis and X-ray structure studies

Variously substituted coordinating rigid rods have been synthesized which incorporate a central 4,7-phenanthroline nucleus attached to two 2-pyridyl groups via its 3 and 8 positions, so as to yield bisbidentate chelates, the two-coordinating axes of the chelates being parallel to one another. Regardless of the nature of the substituents borne by the rods, the copper(I)-induced threading reaction of two such rods through the rings of two bis-macrocycles affords in a quantitative yield the 4-copper(I) threaded assembly. The [2]pseudorotaxane tetramers thus obtained have been fully characterized in solution and, for one of them, an X-ray structure could be obtained, confirming the threaded nature of the complex and providing important structural information.
