title: Survival and extinction of delocalized ring currents in clamped benzenes.
abstract: Direct visualisation of induced current density in clamped benzenes 1-4 distinguishes between saturated clamping groups, for which the central benzene ring retains a conventional diamagnetic ring current, and strongly interacting, unsaturated clamps, for which the central ring supports only the localised circulations expected of a 1,3,5-cyclohexatriene with fully fixed double bonds.
