Summary: This study investigates the synthesis of Mn-based metal-organic frameworks (MOFs), finding that MnMOF-1 is a kinetic or metastable phase, while a newly identified 2D layered material, MnMOF-2D, is the thermodynamically favored product. It is also shown that using longer linkers can help to form more stable structures. In addition, two new porous 3D Mn-based MOFs were successfully synthesized, highlighting the viability of using tetratopic hinged linkers to form 3D MOFs.

Summary: This manuscript reports a highly stable MOF with a cation exchange site synthesized by the reaction between zirconium and mellitic acid under a high concentration of ammonium cations (NH4+). The MOF has four free carboxyl groups, and one of the carboxyl groups acts as a monovalent ion-exchanging site with a high first association constant (pK(a1)). The MOF can reversibly exchange NH4+ with H+, Na+, and K+ cations, and its nanospace enables selective NH4+ recovery from aqueous mixtures, addressing the global nitrogen cycle problem. The proton conductivity of the MOF reaches 1.34 x 10(-3) S cm(-1) at 55 °C by ion exchange from NH4+ to H+.

Summary: Room-temperature synthesis of highly porous M-6-oxocluster-based MOFs including 8- or 12-connected micro/mesoporous solids with different functionalized organic ligands was reported. The compounds showed varying degrees of defects while maintaining the chemical stability of the parent MOFs. The synthesis had a high space-time yield and provided the possibility to tune the particle size for practical use.

Summary: The nuclear industry will continue to develop and produce energy in the foreseeable future, but the disposal of waste radionuclides, particularly radioactive iodine, presents unique challenges due to their volatility and long half-life. Although various adsorbents have been explored, there is still interest in developing novel adsorbents. This review discusses the performance of different porous organic materials for iodine uptake, their synthesis methods, adsorption capacity, reusability, as well as the challenges and prospects in utilizing them for iodine capture.

Summary: Porous aromatic frameworks (PAFs) are versatile porous materials with promising functionality, but the synthesis of PAFs with desired properties is challenging. In this study, a multivariate inspired strategy was employed to successfully synthesize PAFs with highly porous and hierarchical structures. The PAFs obtained through this strategy exhibited both hierarchical structures and high specific surface areas. Furthermore, lipase was loaded onto one of the multivariate PAFs, showing high loading content and favorable catalytic activity and stability.
