Mixing ligands to enhance gas uptake in polyMOFs

Abstract

Polymer-metal organic frameworks (polyMOFs) offer a pathway toward processable polymer–MOF hybrid materials; however, because polymeric ligands are incorporated throughout the MOF lattice, polyMOFs have an inherent shortcoming of reduced pore accessability and surface area compared to traditional MOFs. Herein, a strategy for altering the degree of polymer incorporation in polyMOFs by mixing a multivalent polymer ligand containing MOF-forming linkers with “free” linkers is investigated as a means to tune the properties of polyMOFs, resulting in polyMOFs with superior N2 and CO2 uptake. The mixed ligand approach is further extended to distinct MOF-forming polymer ligands to create multivariate (MTV)-polyMOFs, which provides a method for incorporating low-dispersity polymer ligands with complex architectures into polyMOF lattices without the addition of small molecule components.
