Hydrothermal Synthesis, Crystal Structure And Properties Of The Coordination Polymers With N, O Ligands

Over the past decade, coordination polymers and supramolecular architectures have received much attention in coordination chemistry, crystal chemistry and material chemistry. The fascinating structures of these complexes, coupled with their specific functionality, have made them highly promising in various applications, particularly absorption, catalysis, molecular magnetization and biochemistry. The aim of this work is to investigate how to control the structures and properties of desired coordination polymers and supramolecular architectures. This thesis is divided into four chapters.In the introduction, the concepts, methods and history of coordination polymers are concisely introduced, as well as the current survey and research significance of lanthanide coordination polymers, lanthanide-transition metal coordination polymers and the in situ ligand reaction in hydrothermal conditions.In the second chapter, a series of lanthanide coordination polymers and two transition metal coordination polymers have been described. The results show that: 1) Due to the weak acidity and less solubility of dicarboxylic acid and their complexes, the conditions to hydrothermally synthesize its coordination polymers are relatively critical; 2) The lanthanide triggers the cleavage of C-S bonds in hydrothermal conditions and the existence of strong oxidant changes the product.In the third chapter, a series of lanthanide-transition metal coordination polymers that generated by aromatic carboxylic acid, lanthanide and transition metal salt have been described. The results show that: The temperature of reaction and the choice of the second ligand can affect the structure of the coordination polymers.In the fourth chapter, the hydrothermal synthesis, crystal structure and luminescent properties of a novel homochiral coordination polymer are described. The results show that: the V-shaped dicarboxylate ligand plays a key role in the formation of In-OH-In helical chains, in which the chirality is transferred into the whole three dimensional framework.
