The structures and optical properties of host-guest of cucurbit[n=6,7,8]urils with 2,2'-dipyridine and its derivates have been investigated by 1H NMR technique, UV spectroscopy and fluorescence spectrophotometry. The experimental results reveal that the cucurbit[n=6,7,8]urils can form different host-guest complexes with 2,2'-dipyridine and its derivates, which were included with different ratio by different cucurbit[n]urils.

Key words: cucurbit[n]uril, 2,2'-dipyridine derivate, 1H NMR technique, UV spectroscopy, fluorescence spectro-photometry, host-guest complex
