Synthesis And Study Of The Compound Compoesd Of Polyoxometalates, Rare Earth And ATP

The aim of this thesis is to create a new series of supramolecular polyoxometalate hybrid materials based on Keggin POM clusters and bioactivaty molecules by exploiting appropriate rare earth ions as linkers. These compounds were characterized by XPS, elemental analysis, IR, 31P NMR, TG,and their antibacterial activities have been expolied.A new series of supramolecular polyoxometalate hybrid materials based on Keggin POM clusters(α-SiW11O39)8- as building block and ATP molecules by rare earth ions as linkers have been synthesized, K2LnH2[SiW11O39Ln(ATP*)]·11H2O (Ln=La3+,Ce3+,Pr3+,Nd3+,Sm3+,Eu3+,Er3+)in the routine solution.Preliminary experiments of antibacterial activities have been done to these compounds. The results indicated that these compounds have stronger antibacterial activities.
