摘要
实验结果表明过渡金属离子对八元瓜环的溶解性有影响。在测试浓度范围里,随着过渡金属离子溶液浓度的增加,八元瓜环的溶解度逐渐降低。通过原子吸收光谱法测定表明八元瓜环单晶中含有金属离子,但是晶体结构测定仅找到八元瓜环的结构,尚未发现八元瓜环与过渡金属离子形成自组装结构。
The experimental results reveal that the solubility of cucurbit[8]uril is influenced by concentrations of transition metal ions. The Solubility of Cucurbit[8] urils decreased with increase of concentration of the transition metal ions. It is characterized by atomic absorption spectrometry that there is transiion metal ions in the single crystals of cucurbit[8] uril. However, single crystal X - ray diffraction determination shows that there is no significant interaction between cucurbit[8] uril and transition metal ions.
