Abstract:N-heterocyclic carbenes (NHCs) represent one of the most
promising
ligands for the surface functionalization of metals and for the design
of catalytic materials, but controlling the growth of an ordered self-assembled
monolayer of NHCs has rarely been achieved at the liquid/metal interface.
By means of scanning tunneling microscopy, here we show that the presence
of a liquid phase makes the self-assembled structures of NHCs on the
metal surface highly variable. A few new findings were revealed in
the surface f… Show more
