Herein, a new 2-dimensional coordination polymer based on copper (II), {Cu(L)(DMF)}, where L stands for 1,2,4,5-benzenetetracarboxylate (complex 1) is synthesized. Interestingly, we demonstrate that both solvent and sonication are relevant in the top-down fabrication of nanostructures. Water molecules are intercalated in suspended crystals of complex 1 modifying not only the coordination sphere of Cu(II) ions but also the final chemical formula and crystalline structure obtaining {[Cu(L)(HO)]·HO} (complex 2). On the other hand, ultrasound is required to induce the nanostructuration. Remarkably, different morphologies are obtained using different solvents and interconversion from one morphology to another seems to occur upon solvent exchange. Both complexes 1 and 2, as well as the corresponding nanostructures, have been fully characterized by different means such as infrared spectroscopy, x-ray diffraction and microscopy.
在此，合成了一种基于铜（II）的新型二维配位聚合物{Cu(L)(DMF)}，其中L代表1,2,4,5-苯四羧酸酯（配合物1）。有趣的是，我们证明溶剂和超声处理在自上而下制备纳米结构中都很重要。水分子插入配合物1的悬浮晶体中，不仅改变了Cu（II）离子的配位球，还改变了最终的化学式和晶体结构，得到{[Cu(L)(H₂O)]·H₂O}（配合物2）。另一方面，需要超声来诱导纳米结构化。值得注意的是，使用不同的溶剂会获得不同的形态，并且在溶剂交换时似乎会发生从一种形态到另一种形态的相互转化。配合物1和2以及相应的纳米结构都已通过红外光谱、X射线衍射和显微镜等不同方法进行了全面表征。
