Two 3D Co(II) MOFs of 1,5-naphthalenedisulfonate and bis(benzimidazole) ligands for luminescent sensing of Fe3+ and Cr2O72−

Two Water-Stable Zn(II) Coordination Polymers as Luminescent Sensors for Detection of Uric Acid in Serum, MnO4–, and Cr(VI) Oxo-Anions in Tap Water

“…Recently, the construction of CPs via rigid mixed with flexible ligands has been well documented. − 1,5-Naphthalenedisulfonate (1,5-NDS) is a rigid O-donor ligand with a naphthalene ring as the conjugate system, which has the benefits of construction of CPs with excellent luminescence properties. , Also, its two sulfonate groups can coordinate to metal centers with various modes (Scheme S1), which can help to generate CPs with diverse structures. In addition, 1,4-bis­(2-methyl-1 H -imidazole-1-yl)­butane (Mbimb) and 1,4-bis­(1 H -benzimidazol-1-yl)­butane (bbimb) are two flexible N-donor ligands containing –(CH 2 ) 4 – with good conformational freedom, , thus forming unpredictable intriguing topologies and properties.…”
