A series of lanthanide–organic frameworks [Ln(Himdc)(ina)(H₂O)]_n (Ln = Eu 1a; Sm 1b; and Nd 1c, H₃imdc = imidazole-4,5-dicarboxylic acid, Hina = isonicotinic acid) were synthesized under hydrothermal conditions. All compounds 1a–1c consist of a 3D microporous lanthanide carboxylate ([Eu(COO)₃]_n) framework and uncoordinated Lewis basic pyridyl and imidazole groups hung in the channels. The luminescence investigations show that the compound 1c displays an interesting NIR luminescence property. The compound 1a exhibits a good potential as a luminescent multi-responsive sensing material for Fe³⁺ ions and Cr₂O₇²⁻ anions.

具有路易斯碱性咪唑和吡啶基位点的镧系元素-有机骨架的近红外发射和发光传感

一系列镧系元素有机骨架[Ln（Himdc）（ina）（H ₂ O）] _n（Ln = Eu 1a ; Sm 1b ;和Nd 1c，H ₃ imdc =咪唑-4,5-二羧酸，Hina =在水热条件下合成）。所有化合物1a-1c均由3D微孔镧系羧酸盐（[Eu（COO）₃ ] _n）骨架和悬挂在通道中的未配位的Lewis碱性吡啶基和咪唑基组成。发光研究表明，化合物1c显示出令人感兴趣的NIR发光性质。化合物1a作为Fe ³⁺离子和Cr ₂ O ₇^2-的发光多响应传感材料，具有良好的潜力。
