Herein, a series of azobenzene (Azo)-containing side-chain cyclic polymers were successfully synthesized by combining atom transfer radical polymerization (ATRP) and Cu(I)-catalyzed azide/alkyne cycloaddition (CuAAc) “click” reaction. The aggregates of linear and cyclic Azo polymers in a dichloroethane/limonene mixed solvent were characterized by CD (CD) and UV-visible spectroscopy, demonstrating that the topol. structural constraint and mol. mass of cyclic polymers have clear effects on the supramol. chirality driven by a chiral solvent. The difference between linear and cyclic Azo aggregates in supramol. chirality became less distinct with increasing mol. mass of Azo polymers. The chiroptical switch of cyclic Azo polymers was firstly constructed by trans-cis photoisomerization and cis-trans heating-assisted reorganization processes. These interesting findings suggest that the cyclic topol. has a clear influence on the behavior of supramol. chirality induced by chiral limonene.
