An exceptionally stable Zn<sub>4</sub>O-MOF has been rationally synthesized, which exhibits high CO<sub>2</sub> capture and efficient catalytic conversion for cycloaddition with epoxides under mild conditions.
On the basis of a temperature-induced effect, solvothermal reaction Co(Ac)2·4H2O, 5-amino-2,4,6-triiodoisophthalic acid (H2atibdc), and 1,4-bis(2-methyl-imidazol-1-yl)butane (bib) at 80 °C gave new coordination polymer [Co(bib)(atibdc)] (1), which shows two-dimensional (2D) network with left- right-handed helical chains. By raising temperature to 130 °C, pair homochiral enantiomers [Co(bib)(atibdc)]·2H2O (2, 2M, 2P) were successfully obtained, displaying three-dimensional (3D) framework...

Based on the mixed carboxylate ligands synthesis strategy, an indium-organic framework, (Me2NH2)1.5[In1.5(FBDC)(BDC)]·2.5NMF·CH3CN (1) has been constructed by using (2,5-di(2',5'-dicarboxylphenyl)-difluorobenzene (H4FBDC) and terephthalic acid (H2BDC). Compound 1 contains a 3D intersecting pore system which surface is modified F atoms, it excellent stability in pH = 2-12 aqueous solutions. The activated shows high separation for C2H2/CO2 C2H2/CH4. Moreover, not only strong luminescence but...

Pillar-layered structures represent a significant category within MOFs; however, the exploration of their chemical stability and systematic functionalization has been largely neglected. Herein, we fabricated pillar-layered MOF (Zn-LC–C) with fsc topology, utilizing tetradentate carboxylic ligand bipyridine Zn(II) ions via approach. Notably, this topological structure displays markedly superior compared typical MOFs pcu topology. In addition, by introducing unsaturated bonds to modify...

Different from the conventional method to construct pillared-layer metal-organic frameworks (MOFs) by using mixed bipyridyl and dicarboxylate ligands, herein, we present a new approach build based on pyridyldicarboxylate ligands which were predesigned with certain shape. As exemplified, of 3-(2',5'-dicarboxyphenyl)benzoic acid (H3dbba) 3-(2',5'-dicarboxylphenyl)pyridine (H2dcpy) selected employed three MOFs, [Zn3(dbba)2(bipy)(DMF)]·3DMF·4H2O (1) (bipy = 4,4'-bipyridine), pair crystal...

Using adenine and metal ions to form secondary building units (SBUs), further connected by a highly symmetrical multicarboxylic linker construct an amino-modified porous framework with high porosity, is effective strategy.
