摘　　要：通过X射线衍射、红外光谱、紫外可见光谱和核磁共振等手段,研究了β环糊精(βCD)与阳离子红5GN的包合.分析认为,两者发生了包合,并计算出了包合常数,30℃时一元包合常数为2.35×10-4,二元包合常数为3.29×10-7.By means of X-ray diffraction, infrared spectra , UV-visible spectra and nuclear magnetic resonance spectra, inclusion complexes formation of β-cyclodextrin with cationic red 5GN is investigated. The binding constants are calculated. When the temperature is 30 ℃, the unitary binding constant is 2.35×10^(-4) and the duality binding constant is 3.29×10^(-7).
