different reaction conditions (palladium or copper catalysis) selectively yielded cyclic or acyclic oligomers with n=2–6 (see picture for n=3) linked by freely rotating corner units. STM images of self‐assembled monolayers revealed the difference in the adsorption behavior of the acyclic and cyclic oligomers.
