  bibo_abstract:
  - When charge flows through a molecular circuit, it induces a magnetic field that
    allows the circuit to behave as a nanoscale electromagnet. However, in single-molecule
    circuits this magnetic field is usually weak. Here we show that radially π-conjugated
    carbon structures can support amplified circulating currents that generate local
    magnetic fields. Within tight-binding and density functional theory (DFT) frameworks,
    we first study cycloparaphenylene (CPP) junctions where both electrodes are attached
    to the same phenylene unit on the nanohoop. We observe an energy-dependent ring
    current component that traverses the whole macrocycle by mapping the local current
    density. Importantly, we find that destructive interference near degenerate resonances
    can reverse the ring current direction and amplify it strongly relative to the
    source–drain current. We show that this interference-driven design principle is
    general, and also carries over to C60 junctions. In fullerene, lower-lying degenerate
    resonances are more easily accessible through electrostatic gating, reaching a
    magnetic field of 14.2 mT under a 100 mV source–drain bias. This work thus provides
    new insights into ring currents in radially π-conjugated carbon structures and
    highlights their potential as design platforms for single-molecule electromagnets.@eng
