A water-stable
two-dimensional lanthanide organic framework, {Eu(BTB)DMF}
n
(Eu-MOF; DMF = N,N-dimethylformamide), with two one-dimensional channels was obtained,
and its structure was characterized. With changes in the amount of
LiOH·H2O, different sizes of {Eu(BTB)DMF}
n
were synthesized. The prepared Eu-MOF powder is
easy to disperse in water and exhibits typical Eu red emission. The
fluorescence properties showed that Eu-MOF can detect sulfamethzine
(SMZ) with high sensitivity and selectivity. Finally, the as-synthesized
Eu-MOF was successfully used for the detection of SMZ in surface water
by a standard addition method.
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.
