摘      要：The adsorption structures of 4-cyanophenyl 4-butoxy benzoate(CPBOB) on graphite are studied by Scanning Tunneling Microscope(STM) at room temperature from the mixture of two different liquid crystals. STM images of CPBOB molecules are visualized for the first time with a near-atomic resolution. The adsorption structures are also investigated by molecular dynamical calculation. The STM images of CPBOB are stable in the period of 12 hours. These results indicate that liquid crystals of higher melting point on the surface of graphite can be studied by STM at the room temperature and the CPBOB mnolecules in a unit are orientated in the way of head to head.
