以Dawson型砷钼酸、金刚烷胺为原料,合成了一个新的超分子化合物:(C10H18N)6As2Mo1gO62·6CH3CN·8H2O.通过元素分析,IR,1H NMR等方法对合成的化合物进行了表征.X射线衍射晶体解析表明,金刚烷胺与Dawson型多阴离子以静电力和分子间力(氢键)结合,并且在新化合物中,金刚烷胺及多阴离子结构基本保持不变.该化合物均具有可逆的光致变色特性,基于变色后样品的电子自旋共振(ESR)谱提出一个可能变色机理.以该类化合物为修饰剂的本体修饰碳糊电极(APM-CPE)对过氧化氢还原有很好的电催化活性.

A supramolecular compound with the formula (C10H18N)6As2Mo18O62·6CH2CN·8H2O has been synthesized by the reaction of Dawson type molybdoarsenate acid and amantadine, and characterized by elemental analysis, IR and 1H NMR.The results of X-ray diffraction indicated that amantadine and polyanion were linked together through electrostatic interactions and intermolecular forces (hydrogen bonding).Moreover, amantadine and polyanion preserved their original framework in this new compound.The title compound has a reversible photochromic property.A possible photochromic mechanism was proposed based on the ESR spectra of colour-changed samples.The bulk-modified carbon paste electrode (APM-CPE) using this compound as modifier shows a good electrocatalytic activity toward the reduction of peroxide.

Key words: amantadine, Dawson type polyoxometalate, X0ray crystal structure, photochromism, electrocatalytic activity
