Devices in future could be powered by new “nanohoops”

Tiny circular structures called nanohoops could be used in the future to power a range of devices, according to researchers from the University of Oregon. Cycloparaphenylenes have previously been made only with carbon, but are now being made with a number of atoms. In the journal ACS Central Science, nanohoops could be used in solar cells, organic light-emitting diodes or as new sensors or probes in medicine.
