A new 3D metal–organic framework with (4, 8)-connected AlB2 topology constructed from coordinated evolution of a C3 symmetry ligand

Rare-earth metal–organic frameworks: from structure to applications

In the past 30 years, rare-earth metal–organic frameworks (MOFs) have been gaining attention owing to their diverse chemical structures, and tunable properties.

An acylamide metal-organic framework with an unprecedented four-connecting trinodal topology and amide oxygen coordination

The three-dimensional Zn(II) coordination polymer poly[[bis(μ2-benzene-1,4-dicarboxylato){μ4-N(1),N(3),N(5)-tris[(pyridin-3-yl)methyl]benzene-1,3,5-tricarboxamide}dizinc(II)] monohydrate], {[Zn2(C8H4O4)2(C27H24N6O3)]·H2O}n, is characterized by a rare (4,4,4)-connected (4.6(2).7(2).8)(4.6(2).7(3))(4(2).6(2).7(2)) topology. The tricarboxamide ligand adopts an unprecedented tetradentate coordination mode, with one carboxamide O atom participating in the coordination. The polymer was further characterized by thermogravimetric and solid-state luminescence analysis.

A new metal-organic framework with ultra-high surface area

A new mesoporous MOF, Zn4O(bpdc)(btctb)(4/3) (DUT-32), containing linear ditopic (bpdc(2-); 4,4'-biphenylenedicarboxylic acid) and tritopic (btctb(3-); 4,4',4''-[benzene-1,3,5-triyltris(carbonylimino)]tris-benzoate) linkers, was synthesised. The highly porous solid has a total pore volume of 3.16 cm(3) g(-1) and a specific BET surface area of 6411 m(2) g(-1), adding this compound to the top ten porous materials with the highest BET surface area.

Fast and continuous processing of a new sub-micronic lanthanide-based metal–organic framework

One phase – two processes – two magnitudes for synthesis time and the particle size.
