Trabajo presentado en la IX edición de GEFES, celebrada en Cuenca del 13 al 15 de enero de 2016.
On-surface chemistry has recently emerged as a research field where the catalytic
properties of surfaces are essential tools to synthesize new materials sometimes not
accessible with other techniques [1]. This new approach has high potential for
technological applications and can be a platform for discovering new low dimensional
molecular networks [1-3].
In the present work we employ on-surface chemistry techniques to synthesize a new 2D
material following a bottom-up strategy. We study the thermally activated chemical
reaction of 4-aminophenol (4-AP) induced by the Cu(110) surface in a UHV environment.
4-AP is a good candidate to be used as building blocks for on-surface chemistry due to the
presence of functional groups (-NH2, -OH), each with wide specific chemistry. At room
temperature the adsorbed 4-AP molecules form mainly an ordered monolayer (Fig.1a) on
the Cu(110) surface. The annealing of this monolayer up to 493K induces new chemical
reactions that lead to the formation of polymeric-like structures of 4-AP building blocks
(Fig.1b). The use of different surface techniques such as STM, LEED, NEXAFS and XPS
allows us to obtain structural information of both systems as well as to provide information
on the chemical environment of the atoms. It is confirmed that the use of a combination of
surface techniques is an optimal strategy to gain insight into on-surface chemical reactions
for developing new routes of synthesis for novel materials.
