Abstract: Aromatic belts are hoop-shaped, π-conjugated macrocycles that form the fundamental annular segments of single-walled carbon
nanotubes (SWCNTs). Syntheses of carbon nanobelts have been challenging the chemical community for several decades. The main
reason probably is the possibility that their preparation could open the way to a rational chemical synthesis carbon nanotubes. Here, we
reported a successful synthesis of a belt-shaped carbon nanoring, namely cyclic [6]dianthryltetraphenylacetylene ([6]CAPA), including
two anthraacetylene and four phenylacetylene units. It was prepared in a six-step synthesis via cyclic [6]dianthryltetraphenylethylene
([6]CAPE),with[36]annulene periphery.
