Scanning Tunnelling Microscopic Investigation of Organic Molecular Assembling Systems

QIU Xiao Hui BAI Chun Li ( Institute of Chemistry, Chinese Academy of Sciences, Beijing 100080,China )  
Self assembled organic molecules, including alkylated phthalocyanines, porphyrin and adenine, physisorbed on graphite surface have been stabilized and dispersed on the basal plane of graphite by using linear alkyl substituents as molecular anchors, and have been systematically studied under ambient conditions, with the combination of scanning tunnelling microscopy and molecular mechanics simulation. In addition, scanning tunnelling microscopy measurements have been performed to characterize the conductance behaviour of thiol/Au and phthalocyanines LB films/HOPG, as well as the capillary condensed liquid meniscus formed around tip substrate contact.
