We present a hybrid assembly technique to facilitate the transport measurements of electronic molecules. The technique consists of forming a self-assembled monolayer of the investigated molecule on prepatterned electrodes and then bridging the electrodes with nanoparticles using an alternating electric field. This technique can potentially provide a quick and simple way to screen a large number of electronic molecules. As an example, we report preliminary transport measurements of 1-nitro-2,5-di(phenylethynyl-4*-thioacetyl)benzene as a test molecule. The data show qualitative agreement with previously published results for a similar molecule. © 2002 American Institute of Physics.

    Submonomolecular films deposited onto a metal surface in an electric field exhibit the phenomenon of self-organization. The ordering is manifested by the formation of molecular chains featuring the mass transfer. This results in the appearance of a stable dynamic network structure, which exists...

    The liquid phases of Langmuir monolayers are studied in a simple continuum model in which molecules are treated as flexible chains made up of rodlike segments, with the head confined to the air-water interface. The model is studied within mean-field approximation. We show that both properties of...

    Abstract. We report on a novel kind of self-assembling monolayer (SAM) consisting of large organic molecules on a bimetallic surface. Propylbenzoat reacts with a monoatomically thin rubidium (Rb) layer on a chromium (Cr) film. The interaction between propylbenzoat and Rb and the strong...
