A reduced bis-Schiff base guest containing pyridyl, N,N'-bis(4-pyridylmethyl)-1,6-hexanedi- amine (C6N4), has been synthesized from 4-pyridinecarboxaldehyde and 1,6-hexanediamine. The self-assembled inclusion behaviour of β-cyclodextrin and linear guest C6N4 has been investigated by 1H NMR. Our experimental results revealed that a 1∶1 inclusion complex of β-cyclodextrin and C6N4 could be formed in aqueous solution and the average value of stability constant of inclusion complex was determined to be 1.7×102 dm3•mol－1.

Key words: β-cyclodextrin, reduced bis-Schiff base, inclusion behaviour, NMR technique
