全取代环戊基五元瓜环与铈(Ⅲ)配合物的合成、晶体结构及应用探索

Synthesis,the Crystal Structure and Application of Fully Substituted Cyclopentano Cucurbit[5]uril with Ce(Ⅲ)

利用X-射线单晶衍射分析方法测定了全取代环戊基五元瓜环(CyP5Q[5])和稀土金属铈(Ce3+)形成配合物的晶体结构,结果表明:Ce^(3+)与Cy P5Q[5]的两个端口配位,配合物空腔包结氯离子形成"分子胶囊"结构。相邻的瓜环通过与[ZnCl4]2-的偶极作用,形成一维超分子链。本文通过对该配合物对七种易挥发有机物的吸附进行研究。

Coordination of fully substituted cyclopentano cucurbit[5]uril(CyP5Q[5])with Ce3+in the presence of tetrachloridezicate anions was investigated.Single-crystal X-ray diffraction analysis revealed that the CyP5Q[5]-Ce3+interaction systems an molecular capsule,and that a chloride anion was included in the cavity of the CyP5Q[5]molecule,and[ZnCl4]2-anions in particular played the role of linkers,resulting in the formation of a linear supramolecular.The adsorption of seven volatile organic compounds by this complex was studied.
