Abstract

A novel porous anionic MOF, [H₂N(CH₃)₂][KZn₂(bpyp)(dcba)₂]·DMF·1.5H₂O (Me₂NH₂@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 Eu³⁺/Tb³⁺ ions aqueously encapsulated within the MOF pores. Furthermore, the Tb³⁺ uptake and release was found to be a reversible process and the cationic Tb³⁺ can be gradually released.
