Switchable "on/off" single-molecule magnet (SMM) behavior can be realized in lanthanide metal-organic frameworks (Ln-MOFs) tuned by the temperature-induced change of the coordination geometry of the lanthanide centers.
Benzophenone (BP)
is an ultraviolet filter (UVF) widely used in
personal care products such as sunscreens and cosmetics. Excessive
exposure to BP-type UVFs is a potential threat to human’s health
because of their endocrine-disrupting activity. Water stability of
lanthanide compounds is crucial when they serve as luminescent sensors
because of the practicality and recyclability. In this study, a water-stable
luminescent Zn–Tb heterometallic coordination polymer was rationally
designed and synthesized for rapid detection of BP. This material
showed a high quenching effect, excellent selectivity, and fast response
toward BP.
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.
