The persistence lengths (q) of 9 and 10 were 14.4 and 5.7 nm, respectively, indicatingthat the rigidity of the main chain in 9 can be largely attributed tothe intramolecular inclusion of the polymer main chain into thePM R-CD cavity.
To the best of our knowledge, this is the first reportof the formation of a cholesteric LC phase whose chirality originatesfrom the inclusion of the polymer main chain into the CD cavity.作为刚性的棒状分子,应形成向列相液晶。但是,此时可以看到,在刚性分子嵌套了手性的环糊精后,形成了胆甾相液晶。
