A light-sensitive metal-organic framework composite encapsulated by ion exchange for photocatalytic organic reaction

In this work, ZJU-28, a typical anionic metal-organic framework, was selected as the functional carrier to encapsulate [Ir(ppy)(2)bpy](+) (ppy = 2-phenylpyridine, bpy = 2,2'-bipyridine) cation through ion exchange, and a new composite photocatalyst [Ir(ppy)(2)bpy](+)@ZJU-28 was obtained therefore. The composite material was detailly characterized by powder X-ray diffraction (PXRD), fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), UV-Vis (UV) absorption spectra and ICP-OES. [Ir(ppy)(2)bpy](+)@ZJU-28 showed favorable photocatalytic activity for visible light promoted organic transformations. More importantly, it exhibited super stability and excellent recovery & reuse performance.
