Abstract Rotaxane‐based nanoscale architectures have a huge potential to be processed into widely applied devices. In this work, light‐driven rotaxanes with fluorescent chromophores based on α‐cyclodextrin (α‐CyD) have been doped into amphoteric thermoreversible hydrosol–gels to form a new type of disperse system with reversible optical signals. The photoisomerizations with α‐CyD shuttling have been studied by induced circular dichroism (ICD). Compared with their corresponding solutions, the rotaxane‐doped hydrosol–gel systems produce much more obvious fluorescent binary signals.
