Abstract

The photoinduced interconversion between cinnamido-substituted cyclodextrins constitutes a gating switch through which the substituent moves to open or block access to the cyclodextrin cavity. Most unusually for a cyclodextrin-based device, the operation of this gate is solvent-independent and unaffected by potentially competitive guests. It occurs in MeOH and DMSO, as well as in water. This contrasts with other cyclodextrin inclusion phenomena that are usually driven by hydrophobic effects and limited to aqueous media. Shut the gate: A very unusual cyclodextrin gate has been found that opens and shuts photochemically, instead of being operated by hydrophobic effects and therefore limited to aqueous media.
