Abstract:A tetrazole-naphthalene linker was used to prepare a nickel MOF (metal−organic framework) (NiNDTz) with interesting properties: a specific surface area S BET of 320 m 2 g −1 (S Langmuir 436 m 2 g −1 ), high thermal stability (Td onset = 300 °C), and CO 2 uptake of 1.85 mmolg −1 , attributed to the tetrazole groups to be used as fillers in gas separation membranes. The role of these groups was crucial in the mechanical properties of mixed membranes prepared using polycarbonate as a polymer matrix, providing a v… Show more
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.
