Description

Keigo Nonaka leads a 2026 team building a molecular switch that turns twisted light emission on and off with force alone. The switch is a rotaxane, a ring threaded on an axle, set into the cross links of a double network gel. The ring carries a glowing helicene unit that emits circularly polarized light, whose wave twists as it travels. The axle carries a matching quencher that silences the glow when close.

Swelling and shrinking the gel drags the polymer chains and slides the ring, toggling the glow. Even swelling avoids false signals from specimen alignment, the team notes. Nonaka and colleagues claim the first force control of this emission at the single molecule level, plus a sound way to measure it in soft materials.
