摘要
用饱和溶液法在1∶1的乙醇—水体系中制备了β 胡萝卜素(β C)-β 环糊精(β CD)的准[5]轮烷超分子包合物.紫外可见光度法和元素分析均证明了4轮体的存在.FTIR、X 射线粉末衍射和1HNMR技术为轮烷超分子化合物的形成提供了有力的佐证.
A new pseudorotaxanes formed in 1∶1 alcohol-water solution,by self-assembly of a wire-type molecule β -carotene and four cyclodextrin molecules was reported.Elemental analysis methods proved the existence of -pseudorotaxanes. Meanwhile, characterizations of the pseudorotaxanes were studied by UV-VIS, FTIR. X-ray diffractometry and ^(1)HNMR.
