This paper reports the preparation and characterization of a new aromatic polyazomethine with rotaxane architecture. The complex of β‐cyclodextrin and 1,4‐phenylenediamine was treated with Nn‐butyl‐3,6‐diformylcarbazole, which is large enough to prevent dethreading. The polycondensation reaction was performed in N,N‐dimethylformamide leading to polyazomethine soluble in polar solvents. Measurements made by gel permeation chromatography of the dimethylformamide‐soluble (DMF) soluble polyazomethine show the presence of high molecular weight material. The structure and thermal properties of the resulting polymer were characterized by IR, 1H NMR, TGA and DSC techniques. Copyright © 2003 Society of Chemical Industry
