Synthesis, Crystal Structure, and Luminescence of Zn/Cd Coordination Polymers with a New Fuctionalized Terpyridyl Carboxylate Ligand

“…The design and synthesis of metal–organic frameworks (MOFs) have become a very active area of research, owing to not only their fascinating topological structures , but also their promising applications as functional materials in luminescence, magnetism, absorption, catalysis, ion-exchange, etc. − Although nowadays there exist a variety of coordination polymers which possesses fascinating structures and intriguing properties, it is still a tremendous scientific challenge to predict and synthesize coordination polymers with expected structures and properties due to a number of factors that make a big difference in the formation of MOFs, such as the nature of the metal center and ligand, reaction medium, metal-to-ligand ratio, pH value, and counteranion. − Di- and polycarboxylic acids are widely used as bridging ligands to construct coordination frameworks with versatile structures. − Meanwhile the complexes containing multipyridyl ligands have received much attention in many respects. − At the same time, unprecedented attention has been paid to d 10 metal coordination polymers, as a result of their outstanding photoluminescence. − We are interested in synthesizing coordination compounds on the basis of multipyridyl ligands and d 10 metal ions and have already made advances in this field. − Owing to their electronic and steric versatility and the large π-conjugated structure, 4′-aryl substituted-2,2′:6′,2″-terpyridine still acts as a kind of classical ligands in coordination chemistry. Compared with 2,2′:6′,2″-terpyridine, 4,2′:6′,4″-terpyridine have an advantage that the terminal pyridyl rings can easily stretch out through the coordination bonds between nitrogen atoms and metal centers, generating high-dimensional MOFs.…”

Hole‐Size Relationships in the Assembly of a Furandicarboxylate‐Based Metallolinker in Praseodymium Coordination Polymers Synthesized under Basic Conditions

“…Both roles can work in combination to increase the likelihood of growing crystals suitable for structural determination by XRD techniques. This method is widely used in hydrothermal methods and can also result in varying topologies 12…”

Two new cobalt(II) coordination polymers based on 4′-(2-carboxyphenyl)-4,2′:6′,4″-terpyridine: Syntheses, structures and magnetic properties

“…However, it still remains a great scientific challenge in controlling the final architectures of the products, because the self-assembly process is always influenced by a number of factors, such as the nature of ligand, metal center, reaction medium, metal to ligand ratio, pH value and counter anion [5][6][7][8][9][10]. In order to construct different MOFs with novel structures, judicious selection of metal centers and bridging organic ligands play an important role.…”
