AIE-Active Tetrazolyl Tetraphenylethylene-Based Metal–Organic Framework as Highly Selective Chemosensor for Nitro Explosives

} and 2-fold interpenetrated (4,12)-connected topological networks, respectively. Detailed research on the use of the luminescent MOF with TPE chromophore attached with four tetrazolyl substituents for highly selective fluorescence-based aqueous-phase explosive detection was also conducted. An unprecedented 2D 3-nodal topological network with AIE-active tetrazolyl-tetraphenylethene ligand exhibits promising application prospects in nitro-explosive detection.
