On‐surface orientation and reactivity of diamondoid compounds Površinska orijentacija i reaktivnost dijamantoidnih spojeva

Diamondoids are naturally occurring cage hydrocarbons consisting of fused cyclohexane rings, with their smallest representative being adamantane [1, 2]. Their notable properties include conformational rigidness, thermal stability and low ring strain. Selective functionalization of diamondoids enables their application in medicine, nanotechnology, microelectronics and in development of new carbon‐based materials [1, 2]. Diamondoids are also of use as dispersion energy donors due to their bulkiness and we found that London dispersion interactions between the cages enable precise self‐assembly of diamondoid molecular layers on metal surfaces [3]. Furthermore, we were able to identify the absolute configuration of single chiral diamondoid molecules deposited on a copper surface solely by means of direct visual inspection [4]. In our studies we primarily used high resolution scanning tunneling microscopy (STM) and atomic force microscopy (ATM) in combination with computational tools in order to fully describe our chosen systems and reliably verify the findings. In addition to studying self‐assembly and on‐surface orientation of bulky diamondoids that formed ordered 2D lattices, we also explored reactivity of diamondoid derivatives on metal surfaces upon thermal annealing [5]. Using a chemically well‐controlled approach, we succeeded in building diamondoid chains that consisted of single Cu atoms suspended by the diamantane framework (Figure 1). The implications of such one‐dimensional copper nanowires are of significance in the field of nanotechnology since noble metal chains are expected to be near perfect one‐dimensional conductors.
