Abstract

Abstract : Photoresponsive binding kinetics was achieved in cucurbit[8]uril‐dithienylethene host‐guest complexes. This work demonstrates that, in the presence of a competitor guest (in purple), the host‐guest dissociation kinetics is approximately 100‐fold slower for the closed (green) than for the open (yellow) dithienylethene isomers (t 1/2=107 hours vs. t 1/2=1.2 hours), allowing control over the dissociation rate with red/NIR light.
