The present invention is directed towards a new class of semi-conducting nonacene derivatives. These compounds are all soluble species and they all possess superior resistance to oxidation as compared to their counterparts that lack the substitution patterns disclosed herein.

Take it to the limit: Parent acenes larger than heptacene have eluded synthesis for decades. When 1,2‐diketone bridges in suitably designed tetraketone precursors were removed by irradiation under matrix‐isolation conditions (see scheme), the parent systems of the two next higher acenes were accessible experimentally.
