摘要

The interaction between adenine and #beta#-CD has been investigated in solution and in the solid state by several analytical techniques,primarily by ~1H-NMR,2D ROESY and fluorescence spectra,and secondarily by other important techniques,for example,Fourier transform infraredspectroscopy (FT-IR) and differential scanning calorimetry (DSC).The association constant and 1:1 nature of the complex between adenine and #beta#-CD in solution were determine dby fluorescnece spectroscopy.A spatial configuration for the complex in solution is proposed from analysis of the ~1H-NMR and 2D ROESY data.The Fourier trans form infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) data are consistent with the formation of an inclusion complex.In addition,a solid inclusion complex of adenine wit #beta3-CD was synthesized by the coprecipitation method.
