AB  - The conductivity of a single aromatic ring, perpendicular to its plane, is 
      determined using a new strategy under ambient conditions and at room temperature 
      by a combination of molecular assembly, scanning tunneling microscopy (STM) 
      imaging, and STM break junction (STM-BJ) techniques. The construction of such 
      molecular junctions exploits the formation of highly ordered structures of 
      flat-oriented mesitylene molecules on Au(111) to enable direct tip/pi contacts, a 
      result that is not possible by conventional methods. The measured conductance of 
      Au/pi/Au junction is about 0.1 G(o) , two orders of magnitude higher than the 
      conductance of phenyl rings connected to the electrodes by standard anchoring 
      groups. Our experiments suggest that long-range ordered structures, which hold 
      the aromatic ring in place and parallel to the surface, are essential to increase 
      probability of the formation of orientation-controlled molecular junctions.
