Instead of assembling these molecules step by step, the researchers used a “skeletal transformation” technique that cuts and reshapes the internal framework of existing carbon molecules. This breakthrough allowed them to produce complex chiral nanocarbons that were previously extremely difficult to synthesize. The new approach generated large carbon structures containing up to 170 carbon atoms arranged in unusual figure-eight and bathtub-like shapes. These intricate molecular architectures expand the range of carbon materials available for future technologies. More importantly, their unique electronic behavior makes them promising candidates for advanced electronic devices.
