First switchable graphene nanoribbon developed, capable of twisting on demand

Researchers have created a graphene nanoribbon that can dynamically switch its twist (chirality) using a natural solvent. This breakthrough, published in Nature Communications, overcomes previous limitations in controlling the twist of [4]helicene units in graphene structures. The ability to switch between right-handed and left-handed twists on demand opens up new possibilities for advanced optical switches, chemical sensors, and spintronic components that can adapt to changing environments.
