Expanding the scope of diamond surface chemistry: Stille and sonogashira cross-coupling reactions

Original language description

Well-defined covalent surface functionalization of diamond is a crucial, yet nontrivial, matter because of diamond’s intrinsic chemical inertness and stability. Herein, we demonstrate a two-step functionalization approach for H-terminated borondoped NCD films, which can lead to significant advances in the field of diamond hybrid photovoltaics. Primary diamond functionalization is performed via electrochemical diazonium grafting of in situ diazotized 4-iodoaniline. The freshly grafted iodophenyl functional moieties are then employed to couple a layer of thiophene molecules to the diamond surface via two well-established Pd-catalyzed cross-coupling reactions. XPS analysis indicates a dense coverage and successful cross-coupling. We find that the Stille reaction is accompanied by severe surface contamination, in spite of process optimization and thorough rinsing. Sonogashira cross-coupling provides a clean, high quality functionalization over a broad range of reaction conditions.n
