Abstract
The reaction of (S)-proline with two-dimensional Ni nanoclusters on
Au(111) results in the formation of ordered structures constructed from
two distinct types of nickel prolinate complex. Scanning tunnelling
microscopy and density functional theory are combined to analyse the
supramolecular arrangements produced as a function of annealing
temperature. Octahedral Ni(pro)3 complexes are the fundamental building
blocks of multiple phases identified by the formation of hexagonal pores
of 1 nm diameter. Coexisting with the hexagonal porous phases is a
honeycomb phase constructed from Ni(pro)2 complexes. In contrast to the
thermal stability of the hexagonal porous phases, the honeycomb phase
transforms on heating to a mesh phase which is concluded to be
constructed from pro-pro dipeptide species coordinated to Ni ions. At
even higher temperature, more extensive oligomerisation occurs to
produce an ordered rose phase whose structure is consistent with the
formation of oligoproline species.
