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.

Keywords: dithieno[2,3-b:3',2'-d]thiophene, dioctyl-hexathia[7]heterohelicene, heterohelicene, synthesis, photocylization, crystal structure
