摘要：
In this article, a nanorod suprastructure constructed by coordination of calcium ions (Ca2+) with complex beta-cyclodextrin-4,4'-dipyridyl (B-44) in the presence of the photo-acid merocyanine (MEH). The suprastructure (B-44-Ca) possesses reversible photoswitching with high on/off contrast based on the self-assembly process in aqueous solution. In which, the supramolecular can be activated by visible-light instead of acid or base. The system not only can be carried by remote control, but also by the introduction of additional chemicals, which will facilitate the reversibility of light-controlled supramolecular smart materials.
