摘要：以甲基-β-环糊精（MCD）与芘（Pyr）为原料，通过饱和溶液法制得甲基-β-环糊精与芘的包合物（INC）。
利用紫外光谱（UV）、红外光谱（IR）、热重-差热分析（TG-DSC）、扫描电镜（SEM）及 X 射线粉末衍射（XRD）
等对其结构与性能进行了表征与测试。对不同温度下 INC 的紫外光谱和红外光谱进行了考察。结果表明：当制
备温度为 25 ℃时，INC 包合率最高，为 39%，在 240 nm 处对应吸光度最大，为 1.62 a.u.；IR 检测到受包合物
形成的影响，包合物 INC 中芘的特征峰强度变低、峰形变宽或发生位移；TG-DSC 表明，芘占据甲基-β-环糊精
的空腔生成了包合物；SEM、XRD 显示，包合物出现一组新的特征衍射峰，2θ=11.73、18.04、20.56，表明
包合物晶型改变；甲基-β-环糊精与芘可形成稳定的包合物，当温度为 25 ℃时，甲基-β-环糊精使芘在水中的质
量浓度增加到 7.36 mg/L，为 15 ℃时的 2 倍。

Abstract: Inclusion complex (INC) of methyl--cyclodextrin (MCD) with pyrene (Pyr) was prepared by
saturated solution method, and characterized by ultraviolet spectroscopy (UV), infrared spectroscopy (IR),
thermal gravimetric analysis (TG), differential thermal analysis (DSC), scanning electron microscope
(SEM), X-ray diffraction (XRD) and other techniques. The results showed that the inclusion complex INC
achieved the highest inclusion efficiency (39%) at 25 ℃. At 240 nm, the corresponding absorbance was the
largest (1.62 a.u.). IR results indicated that the characteristic peak intensity of pyrene in INC decreased, the
peak became wider or produced a noticeable displacement. TG-DSC results revealed that pyrene could
enter into the interior of the cavity of β-cyclodextrin molecule, which promoted the formation of inclusion
complex. XRD results displayed that a series of new characteristic diffraction peaks of inclusion complex
appeared at 11.73, 18.04, 20.56 which revealed the inclusion complex polymorph was changed. It was
found that a stable inclusion complex was formed between methyl-β-cyclodextrin and pyrene when the
temperature was 25 ℃. In addition, methyl-β-cyclodextrin could increase the mass concentration of pyrene
in water, and the mass concentration of pyrene was 7.36 mg/L, two times that of 15 ℃.
Key words: pyrene; methyl-β-cyclodextrin; inclusion complex; water treatment technology and
