Abstract

Recyclable materials for simultaneous detection and uptake of ammonia (NH<inf>3</inf>) are of great interest due to the hazardous nature of NH<inf>3</inf>. The structural versatility and porous nature of metal–organic frameworks (MOFs) make them ideal candidates for NH<inf>3</inf> capture. Herein, the synthesis of a water-stable and porous 3-dimensional Cu^II-based MOF (SION-10) displaying a ship-in-a-bottle structure is reported; the pores of the host SION-10 framework accommodate mononuclear Cu^II-complexes. SION-10 spontaneously uptakes NH<inf>3</inf> as a result of two concurrent mechanisms: chemisorption due to the presence of active Cu^II sites and physisorption (bulk permanent porosity). The color of the material changes from green to blue upon NH<inf>3</inf> capture, with the shifts of the UV/Vis absorption bands clearly seen at NH<inf>3</inf> concentrations as low as 300 ppm. SION-10 can be recovered upon immersion of SION-10⊃NH<inf>3</inf> in water and can be further reused for NH<inf>3</inf> capture for at least three cycles.
