A frequent bipyridyl ligand with dicarboxylic acid anchoring groups

As the building block for the synthesis of organometallic compounds and the dicarboxylic acid anchoring groups are key functional groups to form 3D metal-organic frameworks (MOF)


2,2'-Bipyridine-5,5'-dicarboxylic acid, an isomer to 2,2'-bipyridine-4,4'-dicarboxylic acid, is another bipyridyl structure with dicarboxylic acid anchoring groups at 5,-5'-postions. It is one of the most frequently used heterocyclic building blocks in the synthesis of organometallic compounds and the dicarboxylic acid anchoring groups are key functional groups to form 3D metal-organic frameworks (MOF) which find application in carbon dioxide reduction, organic photocatalysis, water oxidation, antioxidants and lithium- and sodium-ion batteries.

Due to the highly ordered stacking structure of 2,2′-bipyridine-5,5′-dicarboxylic acid (H2bpy) imposed by hydrogen bonding, 2,2′-bipyridine-5,5′-dicarboxylic acid can be employed as anode material showing high specific capacity, good cycle stability, and remarkable rate performance in both lithium and sodium-ion batteries. 2,2′-bipyridine-5,5′-dicarboxylic acid has been reported to possess an ultrahigh initial capacity of lithium-ion battery of 1200 mAh•g-1 at a current density of 200 mA•g-1, and the specific capacity can maintain 550 mAh•g-1 after 100 cycles.

Using 2,2'-bipyridine-5,5'-dicarboxylic acid as the binding ligand, both RuH(H2bpy)(PPh3)2(CO)] (I) and [RuH(H2bpy)(AsPh3)2(CO)] (II) shows excellent radical scavenging properties as potential cancer treating agents with less toxicity on normal cell NIH 3T3 and considerable cyto-toxic activity against HeLa and HepG2 cancer cell lines.
