【Abstract】 A supramolecular compound with the formula (C 10H 18N) 6As 2Mo 18O 62·6CH 2CN·8H 2O 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.更多还原
