Abstract A novel large thiophene-fused polycyclic aromatics 1 based on pyrene 5 has been synthesized, and its structure was confirmed by 1 H NMR, 13 C NMR, MS, UV–vis and elemental analysis. The key steps of the synthesis involved the Stille cross-coupling reaction and followed by selective β - β oxidative cyclization of pendant thienyl rings by FeCl 3 under mild conditions.
