AICD plots of selected neutral, protonated, and deprotonated expanded porphyrins (isovalue of 0.06 au). The large arrows denote the direction of the induced ring current: clockwise for diatropic ring currents and anticlockwise for paratropic ring currents. For the Möbius topologies, the direction of the arrows is more difficult to assess due to the non‐planar geometry.
