A series of transition metal-organic frameworks based on a bipyridinium carboxylate ligand: Syntheses, structures and photoluminescent properties

In this paper, based on a bipyridinium carboxylate ligand 1-(3,5-dicarboxy)-benzyl-1,2-di(pyridine-4-yl)ethylene chloride (H2L+Cl−), eight coordination polymers with five different architectures have been obtained. The result indicated that the structural characteristics of the H2L+ and the reaction temperature simultaneously play important roles in the final structures. Additionally, powder X-ray diffraction (PXRD) and thermogravimetric analyses of complexes 1-8, as well as the solid-state luminescent properties of d10 metal complexes 1-4 at room temperature have also been discussed.306
