Abstract
This paper presents a macrocycle, octamethyl cyclo[4](1,3-(4,6)-dimethylbenzene)[4]((4,6-benzene)(1,3-dicarboxylate) (OC-4), existing as two stable atropisomers (*C*<sub>2v</sub>-OC-4 and *C*<sub>4h</sub>-OC-4) at 298 K. Heating facilitates stepwise conversion of *C*<sub>4h</sub> to *C*<sub>2v</sub>-OC-4 via a *C<sub>s</sub>*-symmetric intermediate (*C<sub>s</sub>*-OC-4). Hydrolysis and esterification influence this conversion. *C*<sub>4h</sub>-OC-4, unlike *C*<sub>2v</sub>-OC-4, binds linear guests and fullerenes efficiently.
