Abstract
Two new luminescent Zn(II) metal–organic frameworks (MOFs) have been solvothermally synthesized from a p-conjugated carbazole-containing pyridine ligand in the presence of auxiliary ligands. Both MOFs were characterized by single crystal X-ray diffraction, infrared spectroscopy, elemental analysis and X-ray powder diffraction. Both MOFs show strong luminescence and their luminescence could be quenched by a series of nitroaromatic explosives. Importantly, they exhibit very highly sensitive and selective detection of picric acid compared to other nitroaromatic explosives.
