A stable Ln(iii)-functionalized Cd(ii)-based metal-organic framework: tunable white-light emission and fluorescent probe for monitoring bilirubin.

ABSTRACT: A novel anionic Cd(ii)-based metal-organic framework, H₂[Cd₉(DDB)₄(BPP)₄(H₂O)₁₄]·4H₂O·2DMA (1), was successfully obtained with a rigid carboxylate ligand 3,5-di(2',4'-dicarboxylphenyl)benzoic acid (H₅DDB) and a flexible pyridyl ligand 1,3-bis(4-pyridyl)propane (BPP). Complex 1 contains two-dimensional (2D) honeycomb structures and one-dimensional (1D) chain structures. The adjacent 2D structures are linked by strong intermolecular hydrogen bonds to form an ABAB 3D supramolecular structure, where the 1D chain structures traverse the channels of the 2D structures. Due to the anionic framework, Ln(iii) ions (Ln = Eu and Tb) can be encapsulated in the framework of 1 by a post-synthetic modification p
