Organic molecules are interesting materials with potential for use in next‐generation optical and electronic devices. It is important to prepare highly oriented molecular wires, since the optical and electrical properties of organic films strongly depend on their molecular orientation. The charge‐transfer‐complex wire of TTF‐TCNQ has been studied for application to molecular wires having quasi‐one‐dimensional conductivity. We have prepared highly oriented TTF‐TCNQ grains using the ionization and electric‐field‐assisted deposition method, and have investigated the growth mechanism of TTF‐TCNQ grains. These results demonstrate that needle‐like TTF‐TCNQ grain growth near the electrodes is controlled both by the electric field between the electrodes and by the ionization of evaporated molecules. © 2002 Wiley Periodicals, Inc.
