Abstract: A chemical substance sensing element 142 for detecting a specific chemical substance included in biological information includes a carbon nanostructure and, because of metal complex or a fluorescent molecule modifying its surface, exhibits substance selectivity and high sensitivity. Of the substances modifying the surface of carbon nanostructures, CoPc reacts with NO and pentane and DAF-2 reacts with NO, as the components contained in the biological information, respectively, and both produce reaction products. The reaction product derived from CoPc changes electric resistance between nodes 154 and 156, and the reaction product derived from DAF-2 generates fluorescence of a specific wavelength when irradiated with excitation light. Therefore, by measuring the change in electric resistance or presence/absence and wavelength of fluorescent of the present element, sensing of NO or pentane is possible.

Abstract: Provided is a method for evaluating an organic material in the order of nanometers. According to the present invention, suggested are a device and a method for evaluating an organic material in the order of nanometers, which have not been established in the prior art. In particular, information on energy in transition processes between electron energy levels in an organic material can be obtained with a spatial resolution power of several nanometers or less from the surface direction thereof or the cross-sectional direction thereof. The present invention can also be applied to evaluation of the interface state generated when different materials are jointed to each other. For example, the gradient of the potential or the electric charge state in the interface between an electrode and an organic layer in a semiconductor organic material or an organic luminous device can be evaluated. On the basis of the results, a band diagram of this element can be prepared.

Abstract: This invention provides a process for accumulating different organic molecular films on oxidized III-V-group compound semiconductor substrates in order to produce a stable, high-quality organic monomolecular film that is three-dimensionally regularly arranged, as well as a process for producing a fine pattern of such organic films. This organic film is formed by immersing a III-V group compound semiconductor substrates in a vessel containing a solution containing phosphonic acid dissolved into a solvent in order to form a self-assembled film, and placing the substrate into a different solution to adsorb metal ions to the surface of the film, or immersing the substrate in a bromide or an acid or alkali solution to denature functional groups, then immersing it in a solution containing organic molecules that are selectively chemically adsorbed to the modified functional groups.
