The cover picture is composed by an assumptive structure model of nitrogen-doped porous carbons synthesized by direct carbonization of a nitrogen-rich zinc glutamate metal- biomolecule framework. The background is made from an experimental transmission electron microscopy image. This cover picture illustrates that gas molecules and metal components released by the help of heating and chemical treatments, forming nitrogen-doped porous carbons. These carbons exhibited high specific surface areas (up to 1619.2 m²/g) and also a large specific capacitance of 140.8 F/g at a current density of 0.25 A/g. More details are discussed in the article by Qiu et al. on page 203–209.

Metal-organic frameworks (MOFs) synthesized based on aromatic polycarboxylic ligand with metal cations of M (M=Mn, Co, Cd, Cu, Zn, ···) have been reported. The synthetic methods, structures and potential applications of the MOFs have also been introduced in details. The potential applications were chiefly recommended in magnetism, gas adsorption, gas separation, photodegradation, catalysis and emission.

Porous carbon materials derived from metal-organic frameworks (MOFs) have been brought into stage due to the intrinsic advantages of MOFs such as high porosity and tailorable structure diversity, which might provide infinite possibility in producing porous carbons with diverse structures and various decorations. In this review, we summarize the performances of MOF-derived carbon materials (i.e. non-doped porous carbons, heteroatoms doped porous carbons, metal/metal oxide decorated porous carbons) and give a detailed discussion about the connections between the properties and four major effects (calcination temperature, loading of additional precursor, post-synthetic treatment as well as intrinsic properties of MOFs).

Metal-Organic Frameworks (MOFs) are promising adsorbents for their numerous active sites, uniform porosity and tailorable structure diversity. And adsorption over MOFs for water purification is an interesting and practical issue considering the importance of qualified water. In this review, we will systematically present the performances of MOFs for inorganic and organic contaminants purification in aqueous phase and give a detailed discussion about their performances, influences and potential mechanisms. We hope it is beneficial to the syntheses, regeneration and reuse of MOF adsorbents and could promote the development of MOFs for water purification.

In this review, we summarize the research progress of PSM of MOFs through click chemistry, including azide-alkyne click reaction and thiol-ene reaction.

Two new MOFs based on bipyrazole were synthesized, and they provide examples of metal-anion coordination and linker-anion hydrogen bonding during the framework assembly.

Two 3D porous heterometal-organic frameworks (HMOFs) with isostructures have been successfully synthesized by utilizing two kinds of 3d metal ions, and their multifunctional properties have also been studied.

Nitrogen-doped nanoporous carbons have been successfully synthesized by direct carbonization of a nitrogen-rich metal-biomolecule framework, and these carbons exhibited high specific surface areas and large specific capacitances, which will further facilitate the exploration of such materials as supercapacitors.

Two isostructural 3D lanthanide-containing MOFs constructed from an unprecedented [Ln₇(μ₃-OH)₈]¹³⁺ (Ln=Gd, Tb) cluster in which the Ln³⁺ ions are arranged in a distorted vertexsharing dicubane-like geometry were obtained based on a rigid tripodal ligand. Furthermore, the magnetic property of 1 and the fluorescent property of 2 were also studied.

A new strategy is proposed to construct a hierarchically porous metal-organic framework via using a multiple-branched semirigid ligand.

An effective functionalization strategy has been developed. Well designed pre-installation of the ligand can easily remain the original MOF stucture under mild conditions. Meanwhile, the insert of active group into MOF can't be achieved by the multi-constituents assembly method rather than the direct way.

They exhibit a 1-D zigzag chain, which can be linked to generate a 2-D layer via the hydrogen bonding interactions (CH···O).

Self-assembly of Mn²⁺ and benzimidazole dicarboxylic acid generates a new two-dimensional MOF with high thermal and water stabilities.

Compound 1 features the 3D pillar-layered framework structures assembled by 2D cerium-organic coordination sheets pillared by β-[Mo₈O₂₆]⁴⁻ clusters. Compound 2 exhibits a 3D supramolecular structure containing [Mo₆O₂₀]⁴⁻ polyoxoanions-based 1D molybdate chains through hydrogen bond interactions. The UV-vis spectra and fluorescence properties of compounds 1–2 have also been investigated in detail.
