Abstract
Using 4'-(4′-pyridyl)-2,2':6′,2″-terpyridine (PYTPY) and 3,5-bis-(3-carboxy-benzyloxy)-benzoic acid (H3bcb) as ligands and transition metals cadmium (II) and iron (III) synthesized two metal organic frameworks [Cd(H2bcb)2(PYTPY)] (1) and [Fe(H2bcb)2(PYTPY)]n (2). The structure was confirmed and characterized by single crystal X-ray diffraction and elemental analysis. The structure analysis shows that complexes 1 and 2 are further connected through π-π interactions and hydrogen bonds to form a 3D supramolecular network. In addition, complex 1 shows high sensitivity to Fe3+, Cr2O72− and nitrobenzene in solutions containing mixed metal ions, anionic groups and aromatic compounds. Which makes it be a promising crystalline material as luminescent probe to Fe3+ Cr2O72− and nitrobenzene. This property makes complex 1 a potential fluorescence sensor for these chemicals. The present investigation clearly demonstrates selective, recyclable detection of lethal environmental pollutants such as Fe3+, Cr2O72− and NB in aqueous media which has relevance in the context of environmental protection and homeland security. Moreover, complex 2 exhibits weak antiferromagnetic interactions at low temperature. It lays a good foundation for the future research and design of molecular based magnets.
