On-surface chemistry: synthesis of azine derivatives with acceptor behaviour

On-surface chemistry is a potential strategy focused on obtaining and developing novel nanomaterials of different dimensionalities with atomic precision. The growth mechanism is based on a bottom-up approach where molecular building blocks are evaporated onto a surface. Therefore, choosing the appropriate surface and precursor we are able to build and…

On-surface chemistry: (cyclo)dehydrogenation of PAH catalysed by coinage metal surfaces

New nanoarchitectures can be built from polycyclic aromatic hydrocarbons (PAH) by exploiting the catalytic properties of some metal surfaces. Actually, this bottom-up approach allows the formation of nanostructures with different dimensionality from the same precursor as a consequence of the diffusion of the PAH on the surface. Thus, by selecting…

New method to synthesize graphene by using C60 as carbon source

In this work, we describe a new protocol to grow high-quality graphene by physical vapour deposition (PVD) using C60 molecules evaporated in ultra high vacuum conditions (UHV) on Cu foils substrates. The quality of the resulting graphene layer has been assessed by the combination of complementary surface characterization techniques. Additionally,…
