Abstract: A novel porous anionic MOF, [H<subscript>2</subscript>N(CH<subscript>3</subscript>)<subscript>2</subscript>][KZn<subscript>2</subscript>(bpyp)(dcba)<subscript>2</subscript>]·DMF·1.5H<subscript>2</subscript>O (Me<subscript>2</subscript>NH<subscript>2</subscript>@MOF-1), having exchangeable cations in 1D channels, has been synthesized and characterized. Specifically, the anionic MOF was shown to be able to serve as both a host and an antenna for protecting and sensitizing extra-framework light-emitting Eu<superscript>3+</superscript>/Tb<superscript>3+</superscript> ions aqueously encapsulated within the MOF pores. Furthermore, the Tb<superscript>3+</superscript> uptake and release was found to be a reversible process and the cationic Tb<superscript>3+</superscript> can be gradually released.
