摘　　要：作者利用紫外吸收光谱法考察了七元、八元瓜环(Q[7、8] )与喹啉、异喹啉、7-甲基喹啉的相互作用。实验表明七元、八元瓜环对喹啉、异喹啉、7-甲基喹啉有包结作用,并用两种方法测定了主客体包结物的包结比及包结常数。The interaction of host-guest of cucurbit[n=7-8]urils with quinoline, isoquinoline and 7-methyl quinoline have been investigated by UV spectra。The results have revealed that quinoline, isoquinoline and 7-methyl quinoline were included by cucurbit[7~8]uril. The stability constants and the interaction ratio of the title complexes have been determined.
