A new crown ether-POM (POM = polyoxometalate) adduct with the molecular formula [(C14- H20O5)4(H3O)3]PMo12O40 ・ 0.5CH3CN (1) was isolated from the mixed solvent of acetonitrile and methanol. The adduct is constructed from Keggin [PMo12O40]3− anions and [(C14H20O5)- (H3O+)] and [(C14H20O5)2(H3O+)] cations via electrostatic and hydrogen bonding interactions. The supramolecular interactions combine the crown ether with oxonium ions. In the [(C14H20O5)- (H3O+)] moieties, the oxonium ions reside out of the planes defined by the oxygen atoms of the crown ether. The [(C14H20O5)2(H3O+)] moieties exhibit a sandwich structure. There exist hydrogen bonds between the oxonium ions of the [(C14H20O5)(H3O)]+ cations and the acetonitrile molecules and the terminal and bridging oxygen atoms of the [PMo12O40]3− anions. The adduct has been used as a bulk-modifier to fabricate a chemically modified carbon paste electrode (MCPE), which displays well-defined cyclic voltammograms with three reversible two-electron redox couples in acidic aqueous solution, and electrocatalytic activities towards the reduction of H2O2 and NO2−.

We report herein, the synthesis, and spectral and electrochemical characterization of a series of phthalocyaninato zinc complexes where two biomedically potential structures; crown ether and phthalocyanine moities were gathered on the same molecule. The effect of number of crown ether moieties on metal ion binding properties, as well as proton sensitivity were investigated by using electronic absorption and fluorescence emission spectra. Spectral behaviors of the zinc phthalocyanine complexes fused with one crown ether; Zn [ Pc (15 C 5)( C 6 H 13)6] and four crown ether; Zn [ Pc (15 C 5)4] in presence of Na + and K + ions were investigated into detail because of host-guest interactions of subjective ions with crown ether moieties, and compared with the crown ether free phthalocyanine; Zn [ Pc ( C 6 H 13)8].
