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). ...

How Reproducible is the Synthesis of Zr-Porphyrin Metal-Organic Frameworks? An Interlaboratory Study

Wendy Lee Queen, Jocelyn Richard Roth, Rawan Al Natour

Metal-organic frameworks (MOFs) are a rapidly growing class of materials that offer great promise in various applications. However, the synthesis remains challenging: for example, a range of crystal structures can often be accessed from the same building b ...

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 ...
