Abstract

With 2-octyl dithieno [2, 3-b: 3', 2'-d] thiophene as raw material, three steps including formylation, McMurry reaction and photocylization were employed to generate dioctyl- hexathia [7] heterohelicene in total yield of 29.9'. The crystal analysis shows that some short intermolecular interactions including S... S and C... S interactions were observed in the crystal of target compound.
