Highly reactive acetylene moieties are susceptible to a wide range of synthetic transformations, allowing   the construction of unprecedented molecular architectures at will. In particular, the oligophenylenes obtained by cycloadditions and transition metal-catalyzed cyclomerizations are highly relevant as versatile precursors for the synthesis of polycyclic p-conjugated scaffolds using various cyclization protocols. While such transformations in solution are well established, comparable processes on surfaces still pose considerable challenges.

In this talk, polycyclic scaffolds with non-benzenoid moieties and their heteroatom-doped counterparts obtained via the above-mentioned transformations of various ethynylated building blocks will be presented. The experimentally observed properties of the compounds will be discussed in relation to their structural features and corroborated by theoretical studies.
