title: Topological ring-currents and bond-currents in the altan-[r,s]-coronenes.
abstract: π-Electron ring-currents for the altans of the four regular [r,s]-coronenes are calculated by the topological HLPM approach. The bond-current pattern of the parent structure is generally preserved in the core of the corresponding altan. Altan-[10,5]-coronene appears to support an anomalous diamagnetic current in its [4n]-periphery. This invites further investigation.
