Using tritopic and ditopic organic linkers derived from the same 2,4,6‐triphenylpyridine core, copper(II) metal‐organic frameworks with different three‐dimensional structures have been successfully synthesized under ambient conditions. The crystalline framework, ᴾᵀᴮMOF ([Cu₃(PTB)₂(H₂O)₃]n , where H₃PTB = 4,4′,4′′‐(pyridine‐2,4,6‐triyl)tribenzoic acid), was observed to be mesoporous in nature and exhibited dual functionalities in the removal of organic dyes. While cationic dyes such as methylene blue and malachite green, which are of different sizes, were adsorbed by ᴾᵀᴮMOF ; anionic dyes such as tartrazine could be effectively degraded via a photo‐Fenton‐like reaction catalyzed by the MOFs under the irradiation of visible light.
