A cyclodextrin-based photoresponsive molecular gate that functions independently of either solvent or potentially competitive guests

Loh, K.Smith, N.Onagi, H.Lincoln, S.Easton, C.2015-12-102015-12-102015Chemistry - An Asian Journal, 2015; 10(11):2328-23321861-47281861-471Xhttp://hdl.handle.net/2440/97223The 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.en© 2015 WILEY-VCH Verlag GmbH & Co.
