A series of multi-functional ligands supported lanthanide-organic frameworks, formulated as [Ln(HL{sub 1})(H{sub 2}L{sub 2}){sub 0.5}(H{sub 4}L{sub 2}){sub 0.5}(H{sub 2}O)].(H{sub 2}O){sub 1.5}.{l_brace}Ln=La (1), Pr (2), Nd (3), Sm (4), Eu (5); H{sub 3}L{sub 1}=5-Sulfosaclicylic acid; H{sub 4}L{sub 2}=N,N'-piperazine (bis-methylene phosphonic acid){r_brace}, have been synthesized by hydrothermal reactions. Single crystal X-ray diffractions and powder XRD patterns confirm they are isostructural. They feature 3D framework structures based on extension of a 'zigzag' inorganic chain by organic linkers. Moreover, the photoluminescence properties of 5 and 3 have been investigated, and they show strong solid-state emissions in the visible and near-infrared (IR) regions at room temperature. - Graphical abstract: Five multi-functional ligands supported 3D lanthanide-organic frameworks have been synthesized and structurally characterized. Compounds 5 and 3 displayed strong solid-state emissions in the visible and near-infrared region at room temperature.
