I'm not entirely sure if I understand – What electrical component could these be used to replace? Could they be used to build single molecule wires, or something like single molecule NAND gates, etc?
Basically they're hoping to achieve some form of novel device, not replace existing components.
This isn't without precedent - we have examples like Hall effect and giant magnetoresistive sensors. Both of these went from "weird quantum phenomenon" to "everyone has a device in their home with a component built on this tech".
... 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.
