This work presents an approach for controlling the 2D self-assembly process of organic molecules by adsorption to reactive vs. inert metal surfaces by reversing the selectivity of bonding sites, which is interesting for future applications.
Hierarchical Dehydrogenation Reactions on a Copper Surface.
The one-by-one scission of the X-H bonds of aromatic amines in a controlled fashion on the Cu(111) surface is realized, paving the way for connecting molecules into complex structures in a more reliable and predictable manner.

It is demonstrated that the adsorption of tetranaphthyl-p-terphenyl precursors on metal surfaces can completely change the cyclodehydrogenation route and lead to obtaining planar benzo-fused perihexacenes rather than double [7]helicenes during solution synthesis.
