. (2016). High temperature postsynthetic rearrangement of dimethylthiocarbamate-functionalized metal-organic frameworks. Crystal Growth and Design, 16 (12),[7067][7068][7069][7070][7071][7072][7073] High temperature postsynthetic rearrangement of dimethylthiocarbamatefunctionalized metal-organic frameworks AbstractA thermally promoted postsynthetic rearrangement has been performed on a zinc IRMOF-9-type framework bearing dimethylthiocarbamate tag groups. The rearrangement was accomplished via conventional heating at 285 °C. Crucially, despite the high temperature, the MOF maintains its high accessible surface area and pore space following thermal treatment. The structures and physical properties of the frameworks were characterized by a combination of single-crystal X-ray diffraction, powder X-ray diffraction, differential thermal-thermogravimetric analysis, and gas sorption analysis. The rearrangement results in a slightly higher level of CO 2 adsorption for the modified MOF but with equivalent heat of adsorption. This work offers new perspectives on postsynthetic rearrangements in MOFs and demonstrates that rearrangements that occur at relatively high temperatures are still compatible with the need to retain the structural integrity and porosity of the framework.

The rearrangement was accomplished via conventional heating at 285 °C. Crucially, despite the high temperature, the MOF maintains its high accessible surface area and pore space following thermal treatment. The structures and physical properties of the frameworks were characterized by a combination of single X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD), differential thermalthermogravimetric analysis (DT-TGA), and gas sorption analysis. The rearrangement results in a slightly higher level of CO 2 adsorption for the modified MOF but with equivalent heat of 2 adsorption. This work offers new perspectives on post-synthetic rearrangements in MOFs, and demonstrates that rearrangements that occur at relatively high temperatures are still compatible with the need to retain the structural integrity and porosity of the framework.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
