Abstract：A new cationic host molecule was synthesized by reaction of the di-amide based macrocycle with methyl iodide and the structure was confirmed by NMR, ESI-MS spectra. The complexation behavior of the di-amide based macrocycles with pyridine N-oxide guests was investigated by means of ESI-MS and 1H NMR. The results showed that the cationic host can not only bind the pyridine N-oxide hosts to form 1∶ 1 pseudorotaxane-like complexes but also have much stronger binding ability than the corresponding neutral hosts.
