Abstract:

A novel Microporous decatungstate was synthesized by using cationic l,10-diaminode-cane as template under mile chemical conditions. This material was constructed from highly ordered hexagonal array of 1,10-diaminodecane and decatungstate polyanions. HR-TEM image showed that the decatungstate polyanions "packed" around the l,10-diaminodecane molecules. XRD pattern confirmed its hexagonal array(a=b=1.718nm,cunaknown). A template mechanism was pro-posed to explain its formation process. It is evidenced that l,10-diaminodecane molecules play a crucial role in templating the inorganic framework. the cationic diaminodecane molecules "bond" decatungstate polyanions on each end via supermolecular interaction and thus form bolarform structure units. These units pack together and a hexagonal phase is constructed.

Key words: Decatungstate, microporous materials, 1,10-diaminodecane, templating synthesis
