Abstract
AbstractA rigid propeller‐shaped conjugated triple macrocycle consisting of two nearly perfectly stacked benzene rings and three linking [5]helicene moieties has been synthesized using a glyoxylic Perkin approach. Analysis of the electron delocalization in this atypical aromatic molecule revealed global aromaticity and a 78 π‐electron circuit along the edge of its triple loop, to the detriment of the two 6 π‐electron circuits in the two stacked benzene rings.
