Thiophene-based building blocks have played a dominant role in establishing the field of organic electronics.[1] It is hard to find any efficient semiconducting polymer that would have no thiophene rings in its structure. At the same time, the presence of sulfur in the molecules, significantly affects and complicates their interaction with the surfaces. In this talk I will summarize our decade long scanning probe microscopy studies of on-surface self-assembly[2] and reactivity[3] of thiophene-contained π-conjugated molecules and present some new results showcasing the behavior of high S/C ratio molecules on surfaces of different reactivity (HOPG/Au/Ag/Cu).
