Construction of ntt-Type Metal–Organic Framework from <i>C</i>₂‑Symmetry Hexacarboxylate Linker for Enhanced Methane Storage

By using a shortened hexacarboxylate linker of <i>C</i>₂-symmetry, a ntt-type metal–organic framework (UTSA-61) was constructed. Powder X-ray diffraction (XRD) crystallographic analysis revealed that UTSA-61 features the connection of the organic linker with four Cu₂ paddlewheels and one large -[Cu₂(O₂CR)₄-H₂O-Cu₂(O₂CR)₄]- cluster. This work confirms that a dendritic hexacarboxylate linker may support two cuboctahedral cages close to each other in ntt-type frameworks. Moreover, removing two ethynyl groups from PCN-61 (the prototypical ntt-type MOF) leads to optimized T-Td/T-Oh cages in UTSA-61 and results in preferable methane uptake than those of previously reported ntt-type MOFs. The activated UTSA-61a therefore exhibits a high methane storage capacity of 244 cm³ (STP) cm^–3 at 298 K and 65 bar, and a high working capacity of 176 cm³ (STP) cm^–3 (between 5 and 65 bar). These results rank UTSA-61a as one of the very few MOFs with both high volumetric methane storage and working capacities, rendering UTSA-61a as a promising adsorbent for on-board methane storage application

Metal–Organic Framework with Functional Amide Groups for Highly Selective Gas Separation

A new three-dimensional microporous metal–organic framework [Cu­(<i>N</i>-(pyridin-4-yl)­isonicotinamide)₂(SiF₆)]­(EtOH)₂(H₂O)₁₂ (<b>UTSA-48</b>, UTSA = University of Texas at San Antonio) with functional −CONH– groups on the pore surfaces was synthesized and structurally characterized. The small pores and the functional −CONH– groups on the pore surfaces within the activated <b>UTSA-48a</b> have enabled their strong interactions with C₂H₂ and CO₂ of adsorption enthalpy of 34.4 and 30.0 kJ mol^–1, respectively. Accordingly, activated <b>UTSA-48</b> exhibits highly selective gas sorption of C₂H₂ and CO₂ over CH₄ with the Henry Law’s selectivities of 53.4 and 13.2 respectively, at 296 K, thereby, highlighting the promise for its application in industrially important gas separation

Solvent Dependent Structures of Hydrogen-Bonded Organic Frameworks of 2,6-Diaminopurine

Three solvent dependent structures of 2,6-diaminopurine in <i>N</i>,<i>N</i>′-dimethylforamide (<b>DAP-1-DMF</b>), water (<b>DAP-2-H</b>_<b>2</b><b>O</b>), and methoxybenzene (<b>DAP-3-CH</b>_<b>3</b><b>OC</b>_<b>6</b><b>H</b>_<b>5</b>) have been structurally characterized. They exhibit different structures because of the different involvement of solvent molecules in the hydrogen bonded frameworks. The DAP molecules tend to be self-assembled with other DAP molecules through hydrogen bonding interactions. DAP has very similar hydrogen bonding interaction patterns to the established DAT group (2,4-diaminotriazinyl), underlying the potential of this new unit for the construction of porous hydrogen bonded organic frameworks

Microporous Lanthanide Metal–Organic Framework Constructed from Lanthanide Metalloligand for Selective Separation of C₂H₂/CO₂ and C₂H₂/CH₄ at Room Temperature

A novel pillar-layer porous lanthanide metal–organic framework [Tb₃(ODA)₃(BPDC)₃Na₂]_<i>n</i>·G_<i>x</i> (<b>UTSA-222</b>, G = guest molecules) was constructed from an organic ligand [1,1′-biphenyl]-4,4′-dicarboxylate (BPDC²⁻) and a lanthanide metalloligand [Tb­(ODA)]⁺ (H₂ODA = oxydiacetic acid). The <b>UTSA-222</b> contains two-dimensional intersecting channels with the Brunauer–Emmett–Teller surface area and pore volume of 703 m² g^–1 and 0.344 cm³ g^–1, respectively, for the activated sample. It shows moderately high adsorption selectivity for C₂H₂/CO₂ and C₂H₂/CH₄ separations at 1 atm and room temperature

Two-Photon Responsive Metal–Organic Framework

Two-photon processing presents a facile means to tailor the properties of materials in three-dimensions. A two-photon responsive metal–organic framework (MOF) has been realized through the incorporation of a photoactive linker into a MOF via a multivariate strategy. The resulting MOF exhibits a significant one-photon and two-photon excited fluorescence change in response to UV light and infrared femtosecond laser, enabling spatial modulation of the fluorescence property of the MOF. It thus demonstrates the capacity of two-photon patterning and imaging inside the crystal, and the formation of three-dimensional two-photon excited fluorescent structure in a high resolution

Highly Interpenetrated Robust Microporous Hydrogen-Bonded Organic Framework for Gas Separation

A hydrogen-bonded organic framework (HOF), HOF-11, has been successfully prepared by the slow diffusion of hexane into a tetrahydrofuran solution of tris­(4-carboxyphenyl)­amine (TCPA). HOF-11 has been characterized by single-crystal and powder X-ray diffraction analysis, which is composed of TCPA ligands connected by the intermolecular hydrogen-bonding interactions in the carboxylic group dimer, showing 11-fold interpenetrated three-dimensional hydrogen-bonded networks in a (10,3)-b topology with the pore size of 6.2 × 6.8 Ų. The permanent porosity of degassed HOF was demonstrated by virtue of the CO₂ sorption and selective gas adsorption

A Microporous Metal–Organic Framework with Lewis Basic Nitrogen Sites for High C₂H₂ Storage and Significantly Enhanced C₂H₂/CO₂ Separation at Ambient Conditions

A novel metal–organic framework (MOF), [Cu₂L­(H₂O)₂]·7DMF·4H₂O [<b>ZJU-40</b>; H₄L = 5,5′-(pyrazine-2,5-diyl)­diisophthalic acid], with Lewis basic nitrogen sites has been constructed and structurally characterized. Owing to the combined features of high porosity, moderate pore sizes, and immobilized Lewis basic nitrogen sites, the activated <b>ZJU-40a</b> exhibits the second-highest gravimetric C₂H₂ uptake of 216 cm³ g^–1 (at 298 K and 1 bar) among all of the reported MOFs so far. This value is not only much higher than that of the isoreticular <b>NOTT-101a</b> (184 cm³ g^–1), but also superior to those of two very promising MOFs, known as <b>HKUST-1</b> (201 cm³ g^–1) and <b>Co-MOF-74</b> (197 cm³ g^–1). Interestingly, the immobilized nitrogen sites in <b>ZJU-40a</b> have nearly no effect on the CO₂ uptake, so <b>ZJU-40a</b> adsorbs a similar amount of CO₂ (87 cm³ g^–1) compared with <b>NOTT-101a</b> (84 cm³ g^–1) at 298 K and 1 bar. As a result, <b>ZJU-40a</b> shows significantly enhanced adsorption selectivity for C₂H₂/CO₂ separation (17–11.5) at ambient temperature compared to that of <b>NOTT-101a</b> (8–9), leading to a superior MOF material for highly selective C₂H₂/CO₂ separation
