(Half) Twisted Science: Researchers Build a Molecular Möbius Strip With Only Half the Twist

Researchers built a 13-carbon ring on an insulating surface and imaged a half-Möbius electronic topology.
The electron cloud twists about 90 degrees per circuit, creating a half-Möbius topology observable in the lowest unoccupied molecular orbital.
The topology can be toggled between half-Möbius states and a planar configuration by voltage changes.
Quantum computer validation supported the half-twisted ground state and topology effects.
The half-Möbius topology imposes unusual boundary conditions on the electron wavefunction.
The study links topology to potential control of magnetic and electronic properties in single molecules.
Researchers used scanning probe microscopy and atomic force microscopy with a CO-functionalized tip for precise imaging.
The experiment occurred on an insulating surface over a gold substrate to isolate the molecule’s intrinsic properties.
The work extends ideas of molecular topology beyond benzene-like rings to controllable half twists.
The article highlights potential future work in larger networks and material applications.
