摘要：
Three isomorphous lanthanide-organic polyrotaxane frameworks [Ln(mtpc)(1.5)(DMA)(H2O)]center dot 2H(2)O [Ln = Tb (1); Dy (2); Er (3)] were assembled and characterized. In 1, the mtpc ligand transfer absorbed energy to Tb3+ center to emit characteristic fluorescence. 1 can act as a fluorescent probe for selectively detecting nitrobenzene and iron(III) ions through luminescence quenching. Importantly, the detection limit of nitrobenzene is on the 15-150 ppm scale.
