| Abstract: | Using bis-cyanopyridyl alkane compounds as guests, three cucurbit[6]uril-based new pseudorotaxanes (2a, 2b and 2c) were synthesised and characterised. The crystal structures for 2a and 2c have been determined and discussed. In addition, formation constants and thermodynamic parameters in aqueous solution, as well as thermal decomposition behaviour in solid state, have been studied by 1H NMR and TGA techniques, respectively. |
