A novel low density metal–organic framework with pcu topology by dendritic ligand

Abstract

A novel low density two-fold interpenetrated MOF-5 analogue with pcu topology, JUC-100, was designed and prepared successfully. It can be regarded as MOF-5 in which half of the Zn(4)O(CO(2))(6) units are replaced by organic 1,3,5-triphenylbenzene segments. JUC-100 exhibits H(2) uptake ability comparable to interpenetrated MOF-5, but relatively low initial isosteric heat of adsorption.

A porous metal–organic framework formed by a V-shaped ligand and Zn(ii) ion with highly selective sensing for nitroaromatic explosives

“…Many efforts have been focused on the design of new structures for chemists and materials scientists. [24][25][26][27][28][29][30][31][32] Recently, Li et al proposed a new strategy to use 30 low-symmetrical ligands to generate novel MOFs. For example, some 6-or 12carboxyl dendritic ligands with C 3 symmetry have been applied to build up more plentiful topologies and robust functionalities in MOFs.…”

“…[24][25][26][27][28][29][30][31][32] Recently, Li et al proposed a new strategy to use 30 low-symmetrical ligands to generate novel MOFs. [24] In this paper, we utilized a V-shaped aromatic ligand 1, 3-di(4-40 carboxyphenyl)benzene (H 2 DCPB) with C 2 symmetry, which just retains one branch of the H 6 TDCPB ligand. Evidently, it is quite interesting to explore and develop such ligands with lowered symmetry to construct a MOF.…”

Carbonization of covalent triazine-based frameworks via ionic liquid induction

“…We are interested in exploring CTFs with small pore size which is of interest for gas separation application such as carbon capture [21][22][23][24][25][26][27] by molecular building block (MBB) strategy. [28][29][30] To be highlighted that applying this concept in POP chemistry is very challenging, as no associationdissociation process occurs during the synthetic process. However, because of the structural characteristic of the monomer, it was compelled to us that this strategy will limit the number of plausible outputs and may allow us to achieve the final awaited structure.…”

Synthesis, characterization, and investigations of some luminescent and catalytic properties of coordination polymers assembled from 5-(Pyridin-3-yl)isophthalic acid

“…From both synthetic and structural aspects, the search for new multidentate organic building blocks toward the construction of functional coordination polymers continues to attract increasing attention, often resulting in novel types of framework materials with intricate topologies and unusual properties [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. These materials can be applied potentially in gas storage, separation, ion exchange, catalysis, sensor, drug delivery, and so on [25][26][27][28][29][30][31][32][33][34][35][36]. To obtain predictable frameworks and properties, a large number of studies are being focused on constructing novel coordination polymers by means of functional metal ions and versatile organic ligands [37][38][39].…”
