Abstract
The rational design of metal–organic frameworks (MOFs) with well-defined and cooperative catalytic microenvironments is essential for improving their performance in heterogeneous catalysis. In this work, a fluorine-functionalized rare-earth metal–organic framework, NUC-162, has been constructed from tetranuclear {Tb2(μ3–OH)2} clusters and fluorinated organic linkers. Single-crystal structural analysis reveals a robust three-dimensional framework featuring permanent porosity and accessible channels. Upon thermal activation, NUC-162a exposes defect-accessible metal sites and multifunctional acid–base functionalities within the confined pore environment. Owing to the combined effects of Lewis acidic terbium…
