The structures of self-assembled pseudorotaxane of cucurbit[n]urils(n=6~8) with some alkyldiamines have been investigated by 1H NMR technique and single crystal X-ray diffraction method. The results reveal that the interaction between cucurbit[6]uril or cucurbit[7]uril and 1,7-diaminoheptane or 1,8-diaminooctane is stronger than that between cucurbit[8]uril and 1,7-diaminoheptane or 1,8-diaminooctane, and the pseudorotaxanes of cucurbit[n]urils with the alkyldiamines were observed. Particularly, in the pseudorotaxane of cucurbit[6]uril with 1,8-diaminooctane, the amino groups of 1,8-diaminooctane are left outside the ports of cucurbit[6]uril.

Key words: cucurbit[n]uril, alkyldiamine, NMR technique, single crystal X-ray diffraction, pseudorotaxane
