Abstract: A field-effect transistor includes a semiconductor layer (14) having a portion functioning as a channel region. The semiconductor layer (14) includes, as its constituent components, a plurality of electrically conductive microparticles (52), organic semiconductor molecules (53) bonded to the microparticles (52) so as to link the microparticles to one another (52), and cyclic molecules. Each of the organic semiconductor molecules (53) includes a ?-electron conjugated chain as its main chain, and the ?-electron conjugated chain is insulated by cyclic molecules.

Abstract: A production method of the present invention is a production method of an organic polymer containing two or more organic ring structures and a chain structure threading through the organic ring structures. This method includes a polymerization step of forming the organic polymer, in which the organic ring structures, which are restricted from moving, are disposed at each of a particular constitutional unit, by polymerizing at least one type of monomers each of which has no ionic functional group that releases a metal ion. The above at least one type of monomers include a monomer (M) containing the organic ring structure and a chain component threading through the organic ring structure.

Abstract: An electronic device of the present invention includes at least one electrode (Au electrode 65) and an organic molecule layer (semiconductor layer 14) formed adjacent to the electrode, and in which charge transfers between the layer and the electrode. The organic molecule layer includes a plurality of first organic molecules containing a conjugated ? electron that composes a ? conjugate plane (64). A plurality of second organic molecules is bonded chemically to a surface of the electrode at an interface between the electrode and the organic molecule layer. The second organic molecule contains a conjugated ? electron that composes a ? conjugate plane (67a). The second organic molecule is a molecule having a structure in which the ? conjugate plane (67a) and the surface of the electrode form an angle within a predetermined range when the second organic molecule is bonded chemically to the surface of the electrode.
