Abstract


Nature created many special materials, which are a class built by multi-carboxylate ligands and transition metal ions coexist, this unique structure to produce some excellent performance. Study, it was found that this material in multi-carboxylic acid group copies its transition metal structures have a huge impact, based on this, people try polycarboxylate transition metal combination, synthesis has a special structure and the nature of the new features Material - polycarboxylic acid transition metal - ligand polymer. View of the latest international research results, through the coordination of the transition metal polymer synthesis research focused on the the succinate ligand coordination position or configuration changes polycarboxylic acids - structure of transition metal coordination polymers System synthesized series - transition metal coordination polymers succinate.
