A study ofGUPT-2, a water-stable zinc-based metal–organic framework as a highly selective and sensitive fluorescent sensor in the detection of Al3+and Fe3+ions

A unique Zn-MOF (GUPT-2) with excellent fluorescence characteristics, which have a highly selective fluorescent probe for Al³⁺and Fe³⁺ions in a pure water system based on the ESIPT process with the LOD values 0.446 and 0.269 μM, respectively.
