Novel benzo crown ether cavitand and benzo crown ether–ferrocenyl host molecules that bind bipyridinium and sodium guest cations

Abstract

The syntheses, co-ordination, and electrochemistry of novel macrocyclic benzo crown ether (6), (8), and benzo crown ether–ferrocenyl (7) host molecules, each containing four benzo-15-crown-5 moieties and, in the case of (7), eight ferrocenyl redox-active centres, are reported; the new hosts bind bipyridinium and sodium guest cations.
