Construction of Two Electroactive (3,24)-Connected rht Metal–Organic Frameworks: Anion-Dependent Charge/Electron and Energy Transfer

By incorporating electroactive triphenylamine units into a hexacarboxylate linker, two zinc-based metal-organic frameworks with 3,24-connected rht net were constructed, demonstrating unique anion-dependent intermolecular charge/electron and energy transfer. The crystals of Zn-MOF-1 incorporating nitrate anions within the framework are red and do not show fluorescence at all, while Zn-MOF-2 containing fluoroborate anions within the framework is colorless and exhibits signific
