Abstract
A [2]-catenane consisting of a bipyridinium cyclophane and a dioxybenzene m acrocyclic polyether has been encapsulated within the supercages of zeolite Y by ship-in-a-bottle synthesis; laser flash photolysis reveals that the c harge-separated species decays in hundreds of microseconds in contrast to t he few picoseconds previously reported for the same transient in acetonitri le.
