The title of the paper is "Helical orbitals and circular currents in linear carbon wires"... ... but they do refer to them as "promising candidates for novel applications" which indicates actual applications are a little way off. Incidentally, although it's easy to write these molecules in text (like C=C=C=C=C=C...) that does not really show the helical orbitals. https://pubs.rsc.org/en/content/articlehtml/2019/sc/c8sc05464a https://pubs.rsc.org/en/content/articlehtml/2019/sc/c8sc0546...
