What's Happening?
Chemists at Oxford University's Department of Chemistry have successfully synthesized a stable cyclocarbon, specifically cyclo[48]carbon, that can be characterized spectroscopically in solution at room temperature. This marks only the second instance of a molecular carbon allotrope being studied under normal laboratory conditions, following the synthesis of fullerenes in 1990. The cyclocarbon was synthesized as a [4]catenane, with the C48 ring threaded through three other macrocycles, enhancing its stability by preventing access to the protected cyclocarbon. Previously, such molecular rings were only studied in the gas phase or at very low temperatures. The achievement was made possible by using threaded macrocycles, selecting a large cyclocarbon with low strain, and developing mild reaction conditions. The cyclocarbon catenane was characterized using mass spectrometry, NMR, UV-visible, and Raman spectroscopy.
