| Abstract: Inorganic-organic hybrid framework assemblies ranging from zeolite-like polymers to multilayered perovskites to biomaterials have been intensively interested because of their interesting prop-erties and potential in various applications such as electrical con-ductivity, magnetism, ion exchange, separation and catalysis. We have explored several ways to design and prepare inorganic chains and networks having organic molecular components and/or met-al-metal interactions by using transition metal ions including rare earth metal ions and organic ligands, and obtained a series of novel transition metal coordination polymers. The following polymers have been prepared and structurally characterized in our laborato-ry:(1) novel transition metal and rare earth metal polymers with nanometer-sized cavities and porous structures; (2) the polymers having one dimensional chain structures, including many helical chains; (3) the polymers with lamellar graphite-like structures and excellent conducting properties; (4) the poly-mers of nano-wire with strong metal-metal interaction in core and organic molecules as stable shell. |
