Abstract
An object of the present invention is to provide an organic thin-film transistor which has an organic semiconductor film produced using a compound having an excellent solubility in organic solvents and has an excellent carrier mobility, a compound, a material for an organic thin-film transistor for which the compound is used, a composition for an organic thin-film transistor, a method for manufacturing an organic thin-film transistor, and an organic semiconductor film. An organic thin-film transistor of the present invention contains a compound which is represented by General Formula (1) or General Formula (2) in an organic semiconductor film (organic semiconductor layer) thereof and has a molecular weight of 3,000 or less. In General Formula (1) and General Formula (2), at least one of R, . . . , or Ris a group other than a hydrogen atom.
