Assembly of a high stable POM-based Cu(I) coordination polymer with visible-light-driven photocatalytic properties

• A new POM-based CuI coordination polymers have been hydrothermally synthesized.
• Compound 1 displays high heat stability, acid and alkali resistance.
• It shows efficient visible-light-driven photocatalytic activities in the degradation of organic dyes.

A new coordination polymer (CP), [(PW12O40)2CuI6(trz)6]·H2O (1), has been prepared by hydrothermal method. Six Cu(I) ions are bridged by six trz molecules and six surface oxygen atoms of PW12 to generate a wheel-type CuI6 cluster, and each CuI6 cluster was capped with two PW12 anions to form a dumbbell-like second building block (SBB). 1 can remain intact in solution with pH range from 1 to 10, boiling water and boiling organic solvents, which shows the high heat stability, acid and alkali resistance. It also shows efficient visible-light-driven photocatalytic activities in the degradation of organic dyes.

A new 3D POM-based Cu(I) coordination polymer has been successfully prepared by in-situ hydrothermal reaction. Compound 1 shows remarkably stability and efficient photocatalytic activities in the degradation of organic dyes.Figure optionsDownload as PowerPoint slide
