“…A phenyl ring was selected as an attachment point to graphene, as based on previous theoretical and experimental studies, a phenyl ring is enough to induce p-p stacking interaction with graphene. [23][24][25] After photoexposure, the BODIPY group could be cleaved, releasing free amines (5a) attached to the graphene surface via weak interactions. An amine group was selected as the target functionality due to its key role in a variety of biological compounds and its potential for targeted binding.…”

In the cross‐plane single‐molecule junctions, the correlation between molecular aromaticity and conductance remained puzzling. Cross‐plane break junction (XPBJ) provides new insight into understanding the role of aromaticity and conjugation to molecules on charge transport through the planar molecules. In this work, we investigated the modulation of cross‐plane charge transport in pyrene derivatives by hydrogenation and substituents based on the XPBJ method that differs from those used in‐plane transport. We measured the electrical conductance of the hydrogenated derivatives of the pyrenes and found that hydrogenation reduces conductance, and the fully hydrogenated molecule has the lowest conductance. Conductance of pyrene derivatives increased after substitution by both electron‐donating and electron‐withdrawing groups. By calculating, the trend in decreased conductance of hydrogenated pyrene was found to be consistent with the change in aromaticity. Electron‐withdrawing substituents reduce the aromaticity of the molecule and narrow the HOMO‐LUMO gap, while electron‐donating groups increase the aromaticity but also narrow the gap. Our work reveals the potential of fine‐tuning the structure of the pyrene molecule to control the cross‐plane charge transport through the single‐molecule junctions.
