Abstract:A charge-assisted hydrogen-bonded organic framework (HOF) FJU-201 is constructed by N,N’-bis(5-isophthalic acid)naphthalimide divalent anion (H2L2-), p-xylene and dimethylammonium. FJU-201 can only crystallize in solutions containing p-xylene, and cannot crystallize in both o-xylene and m-xylene. FJU-201 can also crystallize in xylene mixtures with the content of p-xylene is not less than 50%, which can be used for separating and purifying p-xylene, and it has good recyclability.
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.
