Description
Zhang, Zhang, and a large team tackle a materials nuisance: graphene nanoribbons, atom-precise strips of carbon with tunable electronic gaps, clump together so strongly that single-ribbon devices stay out of reach. Their 2026 shielding strategy wraps each ribbon in a cyclophane, a ring-shaped molecular cage that holds neighbours at bay and, by squeezing, strains the ribbon itself. They synthesised three shielded ribbons with different cage chain lengths, plus model compounds, and probed them with terahertz spectroscopy.
Shorter chains made charge carriers move faster, with short-range mobility climbing from under two hundred to well over three hundred in the reported units as the cage tightened. The gain came thanks to lighter effective carriers and longer times between collisions. Computer estimates confirmed the shorter cages carried higher strain and weaker ribbon-to-ribbon attraction, explaining the clean dispersion.
