A luminescent nanocrystal metal–organic framework for sensing of nitroaromatic compounds

The treatment of Cd(II) ion with the sodium salt of H2atc (H2atc = 2-aminoterephthalic acid) in aqueous solution facilely yields crystal nanorods of metal–organic framework at room temperature. The nanocrystal metal–organic framework (NMOF) of [Cd(atc)(H2O)2]n (NMOF 1) has been realized for the straightforward and highly sensitive sensing of nitroaromatic compounds in ethanol solution by the fluorescence quenching and fluorescence titration experiments.
