Self-assembled organic molecules, including alkylated phthalocyanines, porphyrinand adenine, physisorbed on graphite surface have been stabilized and dispersed on the basalplane of graphite by using linear alkyl substituents as molecular anchors, and have been sys-tematically studied under ambient conditions, with the combination of scanning tunnelling mi-croscopy and molecular mechanics simulation. In addition, scanning tunnelling microscopymeasurements have been performed to characterize the conductance behaviour of thiol/Au andphthalocyanines LB films/HOPG, as well as the capillary condensed liquid meniscus formedaround tip-substrate contact.
