Modulating the stacking modes of nanosized metal–organic frameworks by morphology engineering for isomer separation

Abstract

Modulating different stacking modes of nanoscale metal-organic frameworks (MOFs) introduces different properties and functionalities but remains a great challenge. Here, we describe a morphology engineering method to modulate the stacking...

Two‐Dimensional Metal–Organic Framework Nanosheets: Synthesis and Applications in Electrocatalysis and Photocatalysis

“…With a similar strategy, they also synthesized several functionalized Zr-MONs, Hf-MONs, and Ce-MONs by using D 3h symmetric ligands bearing terpyridine group. [74][75][76] Replacing H 3 BTB with D 4h symmetric nickel-tetrakis(4-carboxyphenyl)porphyrin (Ni-TCPP), and using Zr 6 -cluster (Zr 6 (μ 3 -O) 4 (μ 3 -OH) 4 ) as [78].

“…As the amount of acetic acid increased, the morphology of NU-901 changed from nanosheets to interpenetrated nanosheets, and finally to nanoparticles. [78] Recently, they reported that the modulator not only regulated the growth of Zr-BTB nanosheets, but also played a key role in obtaining twisted or untwisted Zr-BTB nanosheets (Figure 6d). [79] Besides the often observed Zr 6 (μ 3 -O) 4 (μ 3 -OH) 4 cluster, Lin and co-workers reported that Zr-MOF nanosheets composed of unique Zr 12 -node (Zr 12 (μ 3 -O) 8 (μ 3 -OH) 8 (μ 2 -OH) 6 ) [80] and linear dicarboxylate linker can be prepared by employing formic acid and water as modulators (Figure 6e).…”

“…reported that the concentrations of monotopic acid (benzoic acid or acetic acid) and water could modulate the stacking modes of nanoscale NU‐901 (Figure 6c), which is constructed from [Zr 6 (μ 3 ‐O) 4 (μ 3 ‐OH) 4 ] node and 1,3,6,8‐tetrakis( p ‐benzoic acid)pyrene ligand. As the amount of acetic acid increased, the morphology of NU‐901 changed from nanosheets to interpenetrated nanosheets, and finally to nanoparticles [78] . Recently, they reported that the modulator not only regulated the growth of Zr‐BTB nanosheets, but also played a key role in obtaining twisted or untwisted Zr‐BTB nanosheets (Figure 6d) [79] .…”

Infusion of Variable Chemical Structure to Tune Stacking among Metal‐Organic Layers in 2D Nano MOF

“…It is very important to note that structural tunability/adaptability is key feature of MOFs/PCPs. [17][18][19] Apart from such 3D architecture of MOFs, 2D MOFs/PCPs represent one class of materials which are potentially useful in energy storage, optoelectronic property, gas permeation, chemical sensing. [20][21][22][23][24] Structural designability/ tunability remained the most important advantage of such 2D MOFs/PCPs as well.…”

“…Combining organic linkers and inorganic metal node generate such MOFs/PCPs with potential voids. It is very important to note that structural tunability/adaptability is key feature of MOFs/PCPs [17–19] . Apart from such 3D architecture of MOFs, 2D MOFs/PCPs represent one class of materials which are potentially useful in energy storage, optoelectronic property, gas permeation, chemical sensing [20–24] .…”
