Abstract / Description:Metal - organic coordination networks (MOCNs) have attracted wide
interest because they provide a novel route towards porous materials
that may find applications in molecular recognition, catalysis, gas
storage and separation(1,2). The so-called rational design principle -
synthesis of materials with predictable structures and properties - has
been explored using appropriate organic molecular linkers connecting to
metal nodes to control pore size and functionality of open coordination
networks(3-9). Here we demonstrate the fabrication of surface-supported
MOCNs comprising tailored pore sizes and chemical functionality by the
modular assembly of polytopic organic carboxylate linker molecules and
iron atoms on a Cu(100) surface under ultra-high-vacuum conditions.
These arrays provide versatile templates for the handling and
organization of functional species at the nanoscale, as is demonstrated
by their use to accommodate C-60 guest molecules.
Temperature-controlled studies reveal, at the single-molecule level,
how pore size and chemical functionality determine the host - guest
interactions.
