Paratropic ring currents discovered in six-membered rings of conical nanographenes: carboncones

Abstract

The magnetically induced current density in carboncone[1,3] and [1,5] has been determined and visualized, qualitatively in terms of maps of current, and quantitatively in terms of bond current strengths. The divergence of the isotropically averaged Lorentz force density has also been calculated. All these theoretical tools provide a coherent picture of the magnetic response of carboncones, which reveals unusual robust paratropic current loops located in many of the six-membered rings.
