A family of microporous and acid–base Ln-MOFs (1-Ln, Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb) has been synthesized from the H3NTB ligand. 1-Ln can efficiently catalyze both cycloaddition of epoxides with CO2 and one-pot cascade deacetalization–Knoevenagel reactions.
A series of microporous and stable LnMOFs (1-Ln, Ln = La, Pr, Eu, and Tb) has been synthesized from H3NTB ligand. 1-Tb shows the best catalytic activities (yield 99%) for Knoevenagel reactions, providing a unique example to differentiate the role of Ln ions in catalysis.
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.
