First molecular switch encapsulated within the cavities of a zeolite. A dramatic lifetime increase of the charge-separated state.
A [2]-catenane consisting of a bipyridinium cyclophane and a dioxybenzene macrocyclic polyether has been encapsulated within the supercages of zeolite Y by ship-in-a-bottle synthesis; laser flash photolysis reveals that the charge-separated species decays in hundreds of microseconds in contrast to the few picoseconds previously reported for the same transient in acetonitrile.
