Polyaromatic hydrocarbons are model compounds for graphite and have interesting electronic and optoelectronic properties. The synthesis and preliminary characterization of hexaalkyl‐substituted hexa‐peri‐hexabenzocoronenes (see figure) are described. It is shown that they exhibit hexagonal columnar mesophases with remarkably large widths, e.g., 339K for R = nC12H25.
