二茂铁和[3]二茂铁基β-二酮及其Cu(II) 和Zn(II) 配合物已被合成和表征。单晶 X 射线衍射分析证实了 Cu(II) 配合物的分子结构。获得了紫外可见光谱和电化学测量结果。所有新化合物均表现出准可逆和扩散控制的氧化还原过程。根据热重分析（TG）测量，该复合物表现出高热稳定性。通过TG和差示扫描量热技术评估，β-二酮配体和配合物对高氯酸铵（AP）的热降解表现出较高的催化效果，而与添加β-二酮配体或Zn(II)配合物相比，Cu(II)配合物的添加更显着地降低了AP的热分解温度，并释放了更多的热量。我们预计这种含二茂铁基的过渡金属配合物在制备复合固体推进剂高燃速催化剂方面具有重要价值。
Ferrocene and [3]ferrocenophane-based β-diketones and their Cu(II) and Zn(II) complexes have been synthesized and characterized. Single-crystal X-ray diffraction analysis confirmed the molecular structures of the Cu(II) complexes. UV-vis spectroscopy and electrochemical measurements were obtained. All the new compounds showed quasireversible and diffusion-controlled redox processes. The complexes displayed high thermal stability according to the thermogravimetry (TG) measurements. The β-diketone ligands and complexes exhibited high catalytic effects on the thermal degradation of ammonium perchlorate (AP) which was evaluated by TG and differential scanning calorimetry techniques, whereas the addition of Cu(II) complexes lowered the thermal decomposition temperature of AP more dramatically and released more heat compared with the addition of β-diketone ligands or Zn(II) complexes. We expect that this kind of transition metal complexes containing ferrocenyl would has great value in preparing a high burning rate catalyst for composite solid propellants.
