In the following pages, we report on our investigation of the effect of one to four adatom defects at Au(111) and Cu(111) surfaces on the adsorption of [6]H and [6]C, as well as any chirality aspects of [6]H adsorption. Overall, this work paves the way for a more accurate understanding of the self-assembly of organic molecules in real organic-metal systems and thus helps facilitate the path forward to developing more efficient optoelectronic devices.
