Nanocage-Based N-Rich Metal-Organic Framework for Luminescence Sensing toward Fe and Cu Ions.

Luminescent metal-organic frameworks (LMOFs) as sensors showing highly efficient detection toward toxic heavy-metal ions are in high demand for human health and environmental protection. A novel nanocage-based N-rich LMOF () has been constructed and characterized. It is a 2-fold interpenetrating structure built from N-rich {Zn(dttz)} nanocages extended by N-donor ligand Hdpa [Hdttz = 4,5-di(1-tetrazol-5-yl)-2-1,2,3-triazole; Hdpa = 4,4'-dipyridylamine].
