We designed antiferromagnetic spin-1/2 chains in fullerene nanoribbons by introducing extra C60 cages at one of their edges. The resulting odd number of intermolecular bonds induces an unpaired π-electron and hence a quantized magnetic moment in otherwise nonmagnetic nanoribbons. We further reveal the formation of an antiferromagnetic ground state upon the linear arrangement of spin-1/2 C60 cages that is insensitive to the specific structural motifs. Janus fullerene nanoribbons may offer an experimentally accessible route to magnetic edge states in low-dimensional carbon nanostructures, possibly serving as a versatile nanoarchitecture for scalable spin-based devices and the exploration of many-body quantum phases.

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
