Assembly of sandwich-type 3-D supramolecular coordination polymers based on hexa-molybdenum chain and {PMo12O40} heteropolyanion
چکیده انگلیسی


• [PMo12O40]3 − anions as templates lead to a unique sandwich hybrid networks.
• It is the first pure Mo-oxide-based polymers based on hexa-Mo unit's chains.
• Compound 1 shows fluorescent properties in the solid state at room temperature.
• Compound 1 displays good electrocatalytic activity on reduction of H2O2.
• Compound 1 exhibits highly-efficient degradation ability for RhB under UV light.

A {PMo12O40}-directed organic–inorganic hybrid compound H3O[Mo6(bpy)6O17][PMo12O40]·2H2O (1) (bpy = 2,2′-bipyridine) has been hydrothermally synthesized and characterized by the elemental analysis, IR, XRD, TG analysis and single-crystal X-ray diffraction. In compound 1, Keggin heteropolyanions as templates induce the [MoO4(bpy)] complexes to form unusual wave-liked hexa-molybdenum unit's chains, which are further linked to form pure Mo-oxide-based host layers via supramolecular interaction. {PMo12} as guest units is grafted on the host layer to result in Keggin ions layers. The host cation layers and Keggin ions layers alternately array together to form unique sandwich-type supramolecular networks. In addition, the solid state fluorescent properties, and electro- and photo-catalytic behaviors of compound 1 have been studied.

Keggin-type [PMo12O40]3 − anions as templates lead to an unusual hybrid materials, which present the first pure Mo-oxide-based coordination polymers based on hexa-molybdenum unit's chains and {PMo12} cluster. The solid state fluorescent properties, electro- and photo-catalytic behaviors of the compound have been studied.Figure optionsDownload as PowerPoint slide
