摘要：

Poly(azomethine)s with rotaxane architecture containing a blocking group in every structural unit of the polymer chain have been synthesized by polycondensation of 3,6-diformyl-9-butyl carbazole with 1,6-hexamethylenediamine/alpha- or beta -cyclodextrin adducts. As compared with the polymers obtained in the absence of cyclodextrins, these polymers are more hygroscopic and soluble in polar solvents such as dimethylformamide and dimethyl sulfoxide. The infrared, proton nuclear magnetic resonance, gel permeation chromatography and differential scanning calorimetry data support the presence of cyclodextrins in every structural unit of the polymer chain.
