α-oligothiophenes with the planarity of acenes, fully fused oligothienoacenes were synthesized and their properties compared to the nonfused α-oligothiophenes. By employing removable solubilizing groups, our synthetic methodology made it possible to efficiently prepare and purify oligothienoacenes with up to seven fusedrings. The key steps involved the halogen dance reaction and Pd-catalyzed coupling of Bu3SnSSnBu3
