Abstract

Using aryldiazonium salts that are air-stable and easily synthesized, we describe here a one- step, room-temperature route to direct covalent bonds between π-conjugated organic molecules on three material surfaces: Si, GaAs, and Pd. The Si can be in the form of single crystal Si including heavily doped p-type Si, intrinsic Si, heavily doped n-type Si, on Si (111) and Si (100), and on n-type polycrystalline Si. The formation of the aryl-metal or aryl- ...
