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

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

An In-Situ Neutron Diffraction and DFT Study of Hydrogen Adsorption in a Sodalite-Type Metal-Organic Framework, Cu-BTTri

Michele Ceriotti, Wendy Lee Queen, Pascal Alexander Schouwink, Shuliang Yang, Mehrdad Asgari, Olga Trukhina, Safak Bulut, Ilia Kochetygov, Rocio Semino Barbaresi

Herein we present a detailed study of the hydrogen adsorption properties of Cu‐BTTri, a robust crystalline metal–organic framework containing open metal‐coordination sites. Diffraction techniques, carried out on the activated framework, reveal a structure ...

Efficient cleavage of aryl ether C–O linkages by Rh–Ni and Ru–Ni nanoscale catalysts operating in water

Paul Joseph Dyson, Vassily Hatzimanikatis, Duncan Thomas Lindsay Alexander, Antoine Philippe Van Muyden, Ning Yan, Georgios Savoglidis, Sviatlana Siankevich, Safak Bulut

Bimetallic Ru–Ni and Rh–Ni nanocatalysts coated with a phase transfer agent efficiently cleave aryl ether C–O linkages in water in the presence of hydrogen. For dimeric substrates with weaker C–O linkages, i.e. α-O-4 and β-O-4 bonds, low loadings of the pr ...

Metal-Organic-Framework-Derived Co3S4 Hollow Nanoboxes for the Selective Reduction of Nitroarenes

Wendy Lee Queen, Emad Oveisi, Daniel Teav Sun, Shuliang Yang, Li Peng, Safak Bulut

MOF-derived Co3S4/CN hollow nanoboxes (CN=nitrogen-doped carbon) was used to catalyze the chemoselective reduction of nitroarenes to anilines under mild reaction conditions with H-2 as the reducing agent. The catalyst provides high conversion efficiencies ...

Recent Advances of MOFs and MOF‐Derived Materials in Thermally Driven Organic Transformations

Wendy Lee Queen, Shuliang Yang, Li Peng, Safak Bulut

Owing to the almost boundless structural tunability, MOF and MOF‐derived catalysts have recently exhibited structures of higher complexity, and hence, have demonstrated activity in a wide array of organic transformations. These reactions have a broad range ...
