Preparation and assay performance of supramolecule of cyclophane-complexed polyoxometalates supported on the gold surface

A novel supramolecular complex of octamolybdates and cyclodextrin was simply prepared for the first time by self-assembled method under room temperature. Successful formation of the functional material was demonstrated by carrying out analysis on its thin films supported on the gold surface by various electrochemical techniques, based on the redox probe of octamolybdates contained in the assembly. Sensing and assay performance of the final functional films were evaluated in FIA system by determining oxo anions in samples based on the electroactivity of surface-confined molybdenum catalyst.
