瓜环与2,2’-联吡啶衍生物的相互作用
Interaction of Cucurbit[n=6,7,8]urils with 2,2’-Dipyridine Derivates
【摘要】 利用~1H NMR技术、紫外吸收光谱及荧光光谱方法,考察了对六、七以及八元瓜环与多种2,2’-联吡啶衍生物相互作用形成的主客体配合物结构及光学性质.研究结果显示,不同的2,2’-联吡啶衍生物与瓜环作用不仅形成多种不同包结比的稳定包结配合物,且所形成的主客体包结配合物的结构及光谱性质也各不相同;同时用几种方法协同考察起到了互为补充、互为验证的良好效果.
【Abstract】 The structures and optical properties of host-guest of cucurbit[n=6,7,8]urils with 2,2’-dipyridine derivates have been investigated by 1H NMR technique, UV spectroscopy and fluorescence spectropho-tometry. The experimental results reveal that the cucurbit[n=6,7,8]urils can form various host-guest com-plexes with 2,2’-dipyridine derivates, which were included with different ratio by different cucurbit[n]urils and possessed different spectral properties. Thus, several methods using for investigation would get the good results since they can be complementary with each other.
