The synthesis of bis( benzo-21-crown-7)- based "wheel" prepared and then threaded with an anthracene-capped dialkyl salt based "axle" which is then capped with phenyl isocyanate to lock and generate {3} rotaxanes, which were then photolyzed to produce a poly(3)rotaxane VOA the reversible photocyclodimerization of the terminal 9- anthryl moieties (14CC14105).
