Synthesis of molecular motors incorporating para-phenylene-conjugated or bicyclo[2.2.2]octane-insulated electroactive groups
The insulating role of the bicyclo[2.2.2]octane fragment has been theoretically evaluated by comparing the electronic coupling parameter (V ab) in 1,4-bis(ferrocenyl)benzene (1) and 1,4-bis(ferrocenyl) bicyclo[2.2.2]octane (2). The geometries w
