Synthesis of Dectungstate Microporous Materials Using 1,10-diaminodecane as Template

A novel Microporous decatungstate was synthesized by using cationic l,10-diaminode-cane as template under mile chemical donditions,This material was construdted from hoghly ordered hexahonal array of 1,10-diaminodecane and decatungstate polyanions.HR-TEM image ahowded that the decatungstate polyanions"packed"around the l,10-diaminodecane moledules.XRD pattern confirmed its hexagonal array(a=b=1.718nm,cunaknown).Atdlplate mechanosm was pro-posed to explain its formation prodess.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 esch end via supermolecular interation and thus form bolarform struc-ture units.These units pack together and ahexagonal phasa is constructed.
