Abstract
A novel luminescent lanthanide metal organic framework (Ln-MOF) is synthesized by in situ encapsulating Eu3+ ions to partial replace the transition-metal clusters in the channels of CPM-17-Zn nanocrystals. The Eu3+ functionalized zeolite-type MOF hybrid system shows excellent luminescence property and photo-stability in aqueous environment for the sensitization and protection from the host framework. Subsequently, as a highly selective and sensitive sensor, its nanocrystals can be used to detect Cd2+ in aqueous solution. In addition, the possible sensing mechanism based on ion exchange is discussed in detail. This work is one of the few cases for detecting Cd2+ in aqueous solution based on a zeolite-type MOF. The good fluorescence stability, low detection limit and broad linear range in aqueous environment make this probe to be expected to have potential application in intracellular sensing and imaging of Cd2+ potentially.
