Synthesis, Characterization and Photoluminescence of Lanthanide Metal-organic Frameworks, Constructed from Triangular 4,4′,4″-s-triazine-1,3,5-triyl-p-aminobenzoate Ligands

Eight isomorphous metal‐organic frameworks: [Ln2(TATAB)2(H2O)(DMA)6]·5H2O (Ln = Sm (1), Eu (2), Gd (3), Tb (4), Dy (5), Er (6), Tm (7), Yb (8)); TATAB = 4,4′,4″‐s‐triazine‐1,3,5‐triyl‐p‐aminobenzoate, DMA = N,N‐dimethylacetamide), were synthesized by the self‐assembly of lanthanide ions, TATAB, DMA...

Description
Summary:Eight isomorphous metal‐organic frameworks: [Ln2(TATAB)2(H2O)(DMA)6]·5H2O (Ln = Sm (1), Eu (2), Gd (3), Tb (4), Dy (5), Er (6), Tm (7), Yb (8)); TATAB = 4,4′,4″‐s‐triazine‐1,3,5‐triyl‐p‐aminobenzoate, DMA = N,N‐dimethylacetamide), were synthesized by the self‐assembly of lanthanide ions, TATAB, DMA and H2O. Single‐crystal X‐ray crystallography reveals they are three dimensional frameworks with 2‐fold interpenetration. Solid‐state photoluminescence studies indicate ligand‐to‐metal energy transfer is more efficient for compounds 2 and 4 which exhibit intense characteristic lanthanide emissions at room temperature. Eight isomorphous metal‐organic frameworks, [Ln2(TATAB)2(H2O)(DMA)6]·5H2O (Ln = Sm (1), Eu (2), Gd (3), Tb (4), Dy (5), Er (6), Tm (7), Yb (8)) were synthesized and characterized. They adopt 3‐D interpenetrating framework with (105·105·105) topology. Compound 4 exhibits bright green Tb emission upon UV excitation.
