Nanodiamonds, so called diamondoids are carbon clusters with perfect bulk diamond structure and complete hydrogen passivation. Diamondoids can be perfectly size-selected and isomer resolved even in their neutral state. This has made possible a variety of investigations on the size and shape dependence of their electronic structure and optical properties. Functionalization of diamondoids allows including them into solid-state devices. We studied the influence of functionalization, by changing the size of the functionalized diamondoid, by variation of the position of the functional group, and by using different functional groups. Our results show that functionalization can be used to tune the diamondoids HOMO - LUMO gap and to modify their electronic structure.
