Immobilizing amine species in a Cr-MOF for enhanced selectivity in CO2 cycloaddition reactions

Wendy Lee Queen, Jordi Espin Marti, Till Marian Schertenleib, Anita Justin, Jocelyn Richard Roth

After grafting polyalkylamine species onto the ligand within a Cr 3+ -MOF, the material was tested for catalyzing cycloaddition reactions between CO 2 and 1,2-epoxybutane (EB). ...

Post-Synthetic Covalent Grafting of Amines to NH2-MOF for Post-Combustion Carbon Capture

Wendy Lee Queen, Mounir Driss Mensi, Jordi Espin Marti, Till Marian Schertenleib, Miriam Jasmin Pougin, Ilia Kochetygov, Andres Adolfo Ortega Guerrero, Anita Justin

Herein, a post-synthetic modification strategy is used to covalently graft polyamines, including ethylenediamine (ED), diethylenetriamine (DETA), tris(2-aminoethyl)amine (TAEA), and polyethyleneimine (PEI) to the amino-ligand inside of a Cr-MOF, NH2-Cr-BDC ...

A Simple, Transition Metal Catalyst-Free Method for the Design of Complex Organic Building Blocks Used to Construct Porous Metal-Organic Frameworks

Wendy Lee Queen, Jordi Espin Marti, Till Marian Schertenleib, Nazanin Taheri, Ilia Kochetygov, Anita Justin, Jocelyn Richard Roth, Sophia Alessandra Pache

The design of metal-organic frameworks (MOFs) having large pore sizes and volumes often requires the use of complex organic ligands, currently synthesized using costly and time-consuming palladium-catalyzed coupling chemistry. Thus, in the present work, a ...

3D vs. turbostratic: controlling metal-organic framework dimensionality via N-heterocyclic carbene chemistry

Wendy Lee Queen, Emad Oveisi, Mounir Driss Mensi, Till Marian Schertenleib, Shuliang Yang, Mehrdad Asgari, Ilia Kochetygov, Vikram Vinayak Karve, Anita Justin

Using azolium-based ligands for the construction of metal-organic frameworks (MOFs) is a viable strategy to immobilize catalytically active N-heterocyclic carbenes (NHC) or NHC-derived species inside MOF pores. Thus, in the present work, a novel copper MOF ...

A Two Step Postsynthetic Modification Strategy: Appending Short Chain Polyamines to Zn-NH2-BDC MOF for Enhanced CO2 Adsorption

Wendy Lee Queen, Jordi Espin Marti, Mehrdad Asgari, Olga Trukhina, Ilia Kochetygov, Anita Justin

Functionalizing metal–organic frameworks (MOFs) with amines is a commonly used strategy to enhance their performance in CO2 capture applications. As such, in this work, a two-step strategy to covalently functionalize NH2-containing MOFs with short chain po ...

Preparation of Highly Porous Metal-Organic Framework Beads for Metal Extraction from Liquid Streams

Wendy Lee Queen, Emad Oveisi, Daniel Teav Sun, Shuliang Yang, Li Peng, Olga Trukhina, Olga Syzgantseva, Ilia Kochetygov, Anita Justin, Hassan Abedini

Metal-organic frameworks (MOFs) offer great promise in a variety of gas- and liquid-phase separations. However, the excellent performance on the lab scale hardly translates into pilot- or industrial-scale applications due to the microcrystalline nature of ...
