我们提出了一种原位制备光致发光镧系金属凝胶的简单方法。在室温下，将Tb3+或Eu3+水溶液与合成的芳羧基配体（DCn,n= 14,16,18）有机溶液混合，可快速形成一系列镧系金属凝胶。凝胶化实验表明，烷基链较长的配体（DC18）具有较强的凝胶化能力，说明配体分子中非配位基团的结构可以影响自组装过程，从而影响镧系金属凝胶的微观结构和性能。FT-IR测试表明，endcn3与Tb3+或Eu3+的配位相互作用是形成金属凝胶的驱动力。XRD分析表明，dc14金属凝胶具有六角形和四角形的混合堆积模式。所有得到的金属凝胶都显示出镧系配合物的典型发光。特别是在DMF/H2O （v:v =1:1）中，DC18/Tb(NO3)3金属凝胶表现出优异的自支撑、自修复、成膜和流变性能。以芳香族羧酸为配体形成了Tb3+/Eu3+金属凝胶，并表现出优异的发光、自愈、成膜和流变性能。
We have presented a simple method for situ fabrication of photoluminescent lanthanide metallogels. A series of lanthanide metallogels could be rapidly formed through mixing the aqueous solution of Tb3+or Eu3+and organic solution of synthesized aromatic carboxylic ligands (DCn,n= 14, 16,18) at room temperature. The gelation tests revealed that the ligand with longer alkyl chain (DC18) showed stronger gelling abilities, indicating that the structure of non-coordinated groups in ligand molecules could affect self-assembly processes and, hence, the microstructures and properties of lanthanide metallogels. FT-IR measurements demonstrated that the driving force of formation of the metallogels was the coordination interaction betweenDCnand Tb3+or Eu3+. XRD analysis revealed thatDC14metallogels took a mixture of hexagonal and tetragonal packing modes. All obtained metallogels have shown typical luminescent emissions of the lanthanide complex. In particular,DC18/Tb(NO3)3metallogel in DMF/H2O (v:v =1:1) has shown excellent self-supporting, self-healing, film-forming, and rheological properties.Graphical abstractThe Tb3+/Eu3+metallogels have been formed with aromatic carboxylic acids as ligands, and they have shown excellent luminescent, self-healing, film-forming, and rheological properties.
