The self-assembly inclusion complexes of β-cyclodextrin(β-CD) and 4-aminoantipyrine(4-AAP) were respectively prepared by the solution method at a constant magnetic field and a non-magnetic field.The β-CD inclusion complexes were characterized by Fourier transform infrared spectroscopy(FT-IR),differential scanning calorimetry(DSC),atomic fluorescence spectrometry(AFS),X-ray powder diffraction(XRD) and scanning electronic microscopy(SEM).The results indicated that the constant magnetic field could influence the self-assembly clathration of β-CD inclusion complexes and improve the bonding effect between the host and the guest.The self-assembly inclusion complexes were easier to be composed.The cavity structures of the β-CD inclusion complexes arranged more orderly,and the crystallinities of the formed inclusion complexes at a constant magnetic field had an even more improvement.
