Abstract: Provided is an organic transistor material characterized by having a trans-1,4-disubstituted cyclohexane structure derived from a compound represented by Formula (1). In Formula (1), X represents a skeleton in which plural phenylene groups or naphthylene groups are linked directly or via a vinyl group, a condensed polycyclic hydrocarbon skeleton, or a heterocyclic compound skeleton; m, n, p, and q each independently represent 0 or 1; and R1 and R2 each independently represent an alkyl group or haloalkyl group having 1 to 15 carbon atoms. This organic transistor material has high carrier mobility and excellent thermal stability.

Abstract: An object of the present invention is to apply an organic thin-film transistor, which is produced using an organic semiconductor material, to an analog amplifier. The analog amplifier according to the present invention includes: a first amplifier (2) which voltage-amplifies an analog signal to be amplified; and a second amplifier (6) which power-amplifies the thus amplified signal output from the first amplifier to generate a drive signal that drives an equipment (10). The first amplifier includes an organic semiconductor amplifier element, namely an organic thin-film field-effect transistor (4), in which a semiconductor layer forming a channel is composed of an organic semiconductor. An organic semiconductor material is solvent-soluble and thus can be applied to form a film by a printing method such as an ink-jet method. Therefore, the production thereof can be carried out using a simple production facility.
