 Me0V9oc\n\nThe dream of building integrated circuits from single-molecule 
 electronic components has been discussed since the 1970s\, as the ultimate
  in miniaturisation. It is still a remote prospect\, but there have been d
 ramatic advances in our ability to synthesise molecular wires and test the
 ir charge-transport behaviour. This lecture will present some of my group
 ’s recent research on the design\, synthesis and characterisation of mol
 ecular wires. This includes both linear wires\, which mediate charge-trans
 port over several nm with high conductance\, and molecular wire nanorings\
 , which exhibit aromatic or antiaromatic ring currents. Aromaticity was on
 ce thought to be limited to small molecules\, but we have shown that it ex
 tends to rings with circuits of at least 162 π-electrons\, as demonstrate
 d by studies of a 12-porphyrin nanoring. One day\, it may be possible to u
 se structures of this type as single-molecule electronic devices.
