Mesoporous Materials

Interest in mesoporous materials (IUPAC definition: pore size 2–50 nm) has developed dramatically over the last few years, not least because the pore structure of these materials provides an extremely large surface area within a relatively small volume of material. This makes the materials suitable, for example, for catalysis, chemical sensors, and molecular separation.

The following is a selection of recent articles in this field from Angewandte Chemie, Chemistry—A European Journal, Advanced Materials, Advanced Functional Materials, and the European Journal of Inorganic Chemistry.

Synthesis and Electric Properties of a Two-Dimensional Metal-Organic Framework Based on Phthalocyanine

Synthesis and Electric Properties of a Two‐Dimensional Metal‐Organic Framework Based on Phthalocyanine

Complexation of the copper(II) phthalocyanine derivative, having four catechol moieties, with copper(II) ions gave a two-dimensional MOF with hierarchical micro/mesoporous structure. The redox-activity and conductivity of the framework rendered this Cu-CuPc MOF a unique cathode material for the lithium-ion battery system, showing large charge/discharge capacity with high cycle stability.

Unravelling the Redox-catalytic Behavior of Ce4+ Metal–Organic Frameworks by X-ray Absorption Spectroscopy

Unravelling the Redox‐catalytic Behavior of Ce4+ Metal–Organic Frameworks by X‐ray Absorption Spectroscopy

Redox change in Ce MOFs: The mechanism by which hexanuclear Ce4+ metal–organic frameworks act as redox catalysts is studied by X-ray absorption spectroscopy. Up to one Ce4+ ion per cluster can be reduced (see picture) with a corresponding outwards radial shift, while not compromising the structural integrity of the framework. This demonstrates the involvement of the metal node in the catalytic cycle and explains the need for TEMPO as redox mediator in two-electron oxidations.

Cyanido-Bridged FeII–MI Dimetallic Hofmann-Like Spin-Crossover Coordination Polymers Based on 2,6-Naphthyridine

Cyanido‐Bridged FeII–MI Dimetallic Hofmann‐Like Spin‐Crossover Coordination Polymers Based on 2,6‐Naphthyridine

The synthesis, structure, magnetic, and calorimetric spin-crossover (SCO) properties of doubly and triply interlocked iron(II) frameworks based on the bis-monodentate 2,6-naphthyridine ligand are described and discussed in the context of Hofmann-like clathrate SCO compounds.

Metal-organic Frameworks (MOFs) as Functional Supramolecular Architectures for Anion Recognition and Sensing

Metal‐organic Frameworks (MOFs) as Functional Supramolecular Architectures for Anion Recognition and Sensing

Metal-organic frameworks (MOFs) have experienced a tremendous growth during last few decades as porous crystalline molecular materials. The comprehensive effect of structural diversity, tunability and high surface area makes MOFs suitable for multifarious applications. MOFs can act as potential receptors toward various target components including ionic species, small molecules, solvents, explosives etc. Anion recognition remains important phenomena considering many chemical and biological processes. Ligand designing, incorporation of appropriate function groups and post-synthetic modifications are key strategies in MOFs for selective recognition and scavenging of environmentally toxic and detrimental anions (i. e. cyanide, oxo-anions etc.). The main focus of this personal account is on our research towards development and potential applications of MOFs with special emphasis on selective and sensitive anion sensing.
