利用β-环糊精(β-CD)对3-硝基-1,2,4-三唑-5-酮(NTO)钡盐的分子识别能力,用溶液法制得β-CD-(NTO)2Ba复合物纳米线材料,用扫描电镜(SEM)、IR、^13C-NMR、元素分析仪和原子吸收仪对其形貌及结构进行了表征。IR、^13C-NMR、元素分析和原子吸收仪表明,β-环糊精与NTO钡盐形成了1:1的包结复合物;扫描电镜表明,所得到的纳米线长达数厘米,其直径约48nm。根据实验提出了可能的包结方式。
Novel nanotubes of β-CD with barium 3-nitre-1,2,4-triazol-5-onate ((NTO) 2 Ba) were prepared using β-CD recognition of (NTO)2Ba. The morphology and structure were characterized by IB, ^13 C-NMB, elemental analysis, flame atomic absorption spectrometry and SEM. The results show that ( 1 ) the molar ratio of β-CD and(NTO) 2 Ba of inclusion compound is 1 : 1 ; (2) the nanotubes are tetragonal lattice with the diameter of about 48 nm and the length of about a few centlmeters,and grow along [001] axis; (3) the mechanism of the inclusion compound is presumed.
