Research Abstract

The purpose of this investigation was to clarify the dielectric and electronic properties of organic monolayer films, and applied them to conformational molecular memory. Thus, this investigation has been carried out on the basis of the idea of Maxwell-displacement current measurement proposed by the investigators. The investigators analyzed the molecular motion of organic monolayer films using a rod-like polar molecular model, assuming the motion of molecules is ruled by the Boltzmann statistics. They theoretically derived a dielectric constant of monolayers and also analyzed the phase transition of organic monolayers, taking into account the interaction working between polar molecules and water surface as well as the electric repulsive interaction working the constituent molecules. To clarify the interfacial electrostatic behavior of organic films, the investigators also used the Kelvin-Probe method and developed a method for determining the electrostatic space charge distribution at … More the molecular-film/electrode interface, as well as for determining the Distribution of the Electronic Density of States.
Orientational transition process of LCs triggered by conformational change of azobenzene and the molecular motion of azobenzenes in mixed monolayer systems were examined. The results were summarized as follows : (1) The physico-chemical properties of organic monolayers such as dielectric constant, relaxation time can be analyzed using a rod-like polar molecular model. (2) Phase transition of monolayers, such as Sa-Sc transition, can be analyzed using a rod-like polar molecular model. (3) The generalized formula of thermally stimulated current was obtained. (4) Spatial distribution at the metal/film interface and film/film interface can be determined on the order of nano-meter scale by using the relationship between the number of deposited organic molecular films and the surface potentials. Experiments ware performed for electrically insulating Polyimide LB films and semiconducting functionalized PI LB films and phthalocyanine films. (5) Distribution of the Electronic Density of states can be determined from the temperature dependence of the surface potentials. Organic films used in this study were polyimide and phthalocyanines. (6) Spatial charges exit at the interface depending on the kinds of metals and the organic molecules. (7) The I-V characteristic of molecular-film diodes was analyzed taking into account the interfacial phenomena. (8) The orientational transition process could be controlled by the cis-trans photoisomerization of surface azobenzene monolayers. The motion of LC molecules was analyzed based on a continum theory, and the motion of LCs could be examined by a simultaneous measurement of optical transmittance and the capacitance. Less
