“…A the topology framework based on a closely related Cu 4 Cl(−COO) 8 SBU was reported in 2011 [59]. Similar to what has been done for MOF-5, where carboxylates could be substituted by PZ, the tetrazolates were shown to be fully replaced by carboxylates.…”

Metal-organic frameworks (MOFs) have attracted enormous scientific interest over the past two decades due to their high crystallinity, exceptional porosity, high modularity, and diverse functionality [1]. The opportunity to achieve functional materials by design with promising properties, unattainable for solid-state materials in general, distinguishes MOFs from any other class of materials, in particular, traditional porous materials, for example, zeolites [2], mesoporous silica [3], and porous carbon [4]. Concepts such as the node and spacer principle [5] are based on simple geometrical analysis, which is facilitated by direct joining of polyhedral or polygonal nodes and linkers to translate their geometry into nets with predictable topology and structure. The obtained crystalline materials represent well-defined structures that allow for studying the design, synthesis, and properties of materials by means of single-crystal X-ray diffraction. Herein, we introduce the concept of secondary building units (SBUs) [1a] as a critical design element for the synthesis of rigid, permanently porous MOFs. Furthermore, the cluster chemistry of copper and zinc is highlighted due to the depth and diversity of their SBU geometries, which allow them to be used in linking with organic units (reticular chemistry) [6]. These will be introduced and exemplified by prominent MOF structures, demonstrating net topologies that have produced numerous functional and expanded frameworks. Secondary Building Units (SBUs): The Design Principles of MOFsIn contrast to molecular building blocks in general [7], which also include single metal nodes, SBUs are defined as an aggregate of metal ions stitched together by multidentate functional groups, such as carboxylates, into clusters (Figure 3.1) [1a]. The SBU term was coined for MOFs as an analogy to SBUs in zeolite chemistry, which are finite or infinite component units that facilitate the structural diversity The Chemistry of Metal-Organic Frameworks: Synthesis, Characterization, and Applications, First Edition.

“…Due to the electric fields generated inside their nanopores by the presence of extraframeworks ions, ionic MOFs show strong interactions with guest molecules, and specific interactions with polar guests in particular. This effect can in turn be leveraged for applications in gas adsorption and storage, [107,108] separation, [109] molecular recognition, [110] drug delivery, [111] ion exchange [112] and catalysis.

In this introductory review, we give an overview of the computational chemistry methods commonly used in the field of metal-organic frameworks (MOFs), to describe or predict the structures themselves and characterize their various properties, either at the quantum chemical level or through classical molecular simulation. We discuss the methods for the prediction of crystal structures, geometrical properties and large-scale screening of hypothetical MOFs, as well as their thermal and mechanical properties. A separate section deals with the simulation of adsorption of fluids and fluid mixtures in MOFs.

“…The accessible void is estimated by PLATON [19] to be about 24.3% of the total crystal volume. TGA indicates that the solid is thermally stable up to 350°C ( Figure S2), which is higher than the single framework (~300°C) [20]. The improvement of thermal stability could be assigned to the encapsulation of POMs [14c,d].…”

Pore partition effect on gas sorption properties of an anionic metal–organic framework with exposed Cu2+ coordination sites

Abstract: Presented here is an anionic nanoporous framework material with mobile guest cations which can perform ion exchanges with different tetraalkylammonium cations, and the resulting tunable pore structures exhibit interesting pore partition effects on gas storage and separation.
