Supramolecular Assembly through the Highest Connectivity of a Keggin Polyoxometalate

摘要

A novel supramolecular compound based on the Keggin polyoxometalate (Hpipz)31PMoi20401(1) (pipz = piperazine) has been synthesized and characterized. X-Ray diffraction analysis reveals that the Keggin polyanion uses all of its surface oxygen atoms (36) to attract eighteen pipz units at its periphery. This represents the highest connectivity of a Keggin polyoxoanion. The electrochemical behavior of a CPE modified with 1 (1-CPE) has been studied.
