Incorporation of Clathrochelate-Based Metalloligands in Metal-Organic Frameworks by Solvent-Assisted Ligand Exchange

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, José Luis Bila, Ophélie Marie Planes, Pascal Alexander Schouwink

Iron(II) cage complexes with terminal 4-pyridyl groups can be incorporated in metal-organic frameworks (MOFs) via solvent-assisted ligand exchange (SALE). Paddle -wheeled MOFs with N,N'-di-4-pyridylnaphthalenete-tracarboxydiimide pillars were used as start ...

Geometric landscapes for material discovery within energy–structure–function maps

Seyedmohamad Moosavi, Berend Smit, Henglu Xu

Porous molecular crystals are an emerging class of porous materials formed by crystallisation of molecules with weak intermolecular interactions, which distinguishes them from extended nanoporous materials like metal–organic frameworks (MOFs). To aid disco ...

Construction of MOF/Polymer Composites for Metal Ion Capture

Daniel Teav Sun

Metal ion capture is of environmental and economic significance. The industrial revolutions have discharged increasing amounts of heavy and precious metals into complex water sources. The key is that these types of metal ions tend to be at trace amounts in ...

Metal Soap Membranes for Gas Separation

Deepu Joseph Babu, Kumar Varoon Agrawal, Davide Campi, Qi Liu, Jian Hao

Metal soaps or metal alkanoates are metal-organic complexes held together with metal cations and the functional groups of hydrocarbon chains. They can be synthesized at a high yield by simply mixing the metal and organic sources, forming crystalline framew ...

Controlling strategies to maximize reliability of integrated photo-electrochemical devices exposed to realistic disturbances

Sophia Haussener, Saurabh Yuvraj Tembhurne

We numerically investigate the conversion of solar energy into chemical energy by integrated photo-electrochemical (IPEC) devices and assess their response to time-dependent changes in the boundary conditions and the material properties. We focus on a devi ...

A new post-synthetic polymerization strategy makes metal-organic frameworks more stable

Safak Bulut, Emad Oveisi, Mehrdad Asgari, Daniel Teav Sun, Wendy Lee Queen, Li Peng, Olga Trukhina, Shuliang Yang, Abbas Jamali

Metal-organic frameworks are of interest in a number of host-guest applications. However, their weak coordination bonding often leads to instability in aqueous environments, particularly at extreme pH, and hence, is a challenging topic in the field. In thi ...
