“…We selected 3-(pyridin-4-yl)benzoic acid (Hpba) as a short and flexible ligand for generation of small pores [31][32][33][34] . In a few examples, the biphenyllike fragments of organic ligands have been observed to undergo paddlewheel movement or conformation change 35,36 .…”

Direct visualization of a guest-triggered crystal deformation based on a flexible ultramicroporous framework

Host-guest composites may exhibit abnormal and/or controllable physical properties that are unavailable for traditional solids. However, it is still very difficult to control or visualize the occupancy and motion of the guest. Here we report a flexible ultramicroporous coordination polymer showing exceptional guest-responsive thermal-expansion properties. The vacant crystal exhibits constant and huge thermal expansion over a wide temperature range not only in vacuum but also in air, as its ultramicroporous channel excludes air adsorption even at 77 K. More interestingly, as demonstrated by single-crystal X-ray crystallography, molecular dynamic simulations and solid-state nuclear magnetic resonance, it selectively responds to the molecular rearrangement of N,N-dimethylformamide, leading to conformation reversion of the flexible ligand, which transfers these actions to deform the whole crystal lattice. These results illustrate that combination of ultramicroporous channel and flexible pore surface could be an effective strategy for the utilization of external physical and chemical stimuli.

“…M etal-organic frameworks (MOFs) have been recognized as an excellent platform for host-guest chemistry, which includes gas storage [1][2][3][4][5] , ion-exchange [6][7][8][9][10] , separation [11][12][13][14][15][16] , and so on [17][18][19][20][21][22][23] . The pore size of MOFs varies from a few angstroms to a few nanometres, making them ideal for incorporating species ranging from small gas molecules [24][25][26] and organic molecules 27,28 to large inorganic and organic species [29][30][31][32] .…”

Selective anion exchange with nanogated isoreticular positive metal-organic frameworks

Crystalline porous materials, especially inorganic porous solids such as zeolites, usually have negative frameworks with extra-framework mobile cations and are widely used for cation exchange. It is highly desirable to develop new materials with positive frameworks for selective anion exchange and separation or storage and delivery. Recent advances in metalorganic framework synthesis have created new opportunities in this direction. Here we report the synthesis of a series of positive indium metal-organic frameworks and their utilization as a platform for the anion exchange-based separation process. This process is capable of size-or charge-selective ion-exchange of organic dyes and may form the basis for size-selective ion chromatography. Ion-exchange dynamics of a series of organic dyes and their selective encapsulation and release are also studied, highlighting the advantages of metal-organic framework compositions for designing host materials tailored for applications in anion separation and purification.

“…Metal-organic frameworks (MOFs) with various structures have received tremendous attention because of their potential applications in catalysis, luminescence, magnetism, gas storage and separation and so on [1][2][3][4]. Although a variety of MOFs have been successfully synthesized, rational control in constructing of coordination polymers with desired frameworks and properties remains a great challenge in crystal engineering.…”

Source of materialA mixture of Zn(Ac) 2 · H 2 O (43.9 mg, 0.2 mmol), adipic acid (29.2 mg, 0.2 mmol), NaOH (8.0 mg, 0.2 mmol) and 1,4-bis(2-methylbenzimidazol-1-ylmethyl) benzene (36.6 mg, 0.1 mmol) in 10 mL distilled H 2 O was sealed in a 25 mL Te on-lined stainless steel container and heated at 160°C for 4 days. After the mixture was cooled to room temperature at a rate of 5°C/h, colorless block crystals were obtained with a yield of 56% (based on Zn).
