Although atropisomers with chiral axes based on second-row elements (e.g., biaryls) are common, stable atropisomerism around a long, flexible axis involving heavier elements remains rare. Here, we introduce stable atropisomers featuring a carbon–iodine bond as a sole chiral axis, achieved through pairing a rigid benziodoxole scaffold with a bulky fused aryl group. These molecules exhibit thermally robust atropisomerism, with rotational barriers over 30 kcal mol<sup>–1</sup> and racemization half-lives surpassing 50 years. Notably, these C–I atropisomers exhibit acid-responsive racemization rates that vary with acidity, enabling semi-static or dynamic atropisomerism.
