【摘要】 应用饱和水溶液法制备β3-CD-百里香酚包合物。表征结果可知:扫描电镜(SEM)照片从晶体形态上表明了包合物形成有别于β3-CD及其水合物氢键型晶格的结构;综合热分析(SAT)包合物中环糊精疏水内腔存在的高能水的消失及红外光谱分析(FTIR)中百里香酚的酚羟基包含于主体空腔中验证了β-CD百里香酚包合物的形成。另一方面,通过结构力学原理对百里香酚分子大小进行测算,初步构造包合物的β-CD-百里香酚主客体包合结构分子示意图。更多还原

【Abstract】 Theβ-cyclodextrin-thymol inclusion complexes were prepared by the saturated water solution method.The characterization results showed:the SEM micrographs indicated the lattice ofβ-CD-thymol inclusions was different from hydrogen-bond-type crystal lattice whichβ-CD andβ-CD-water inclusions were categorized into;in SAT data the disappearance of high-energy water molecules,which were used to be in theβ-CD cavity,and phenolic hydroxyl of the thymol included in theβ-CD cavity in the FTIR data supported a successful formation of the inclusion.Besides,according to the calculation of chemical structure, molecular size of thymol was estimated and the preliminary structure of host-guest inclusions was constructed.更多还原
