The present invention provides a solvent or a solvent composition for producing an organic transistor which is excellent in solubility in an organic semiconductor material and which can form an organic transistor having high crystallinity. The solvent or solvent composition for producing an organic transistor of the present invention is a solvent or a solvent composition for dissolving an organic semiconductor material, and comprises a solvent A represented by the following formula (A). In the formula (A), R1 is a C1-4 alkyl group, a C1-4 alkyl group, a C5-6 cycloalkane ring, a C5-6 cycloalkenyl ring, a C6-12 aryl group, or a combination of two or more thereof. base. R2, R3, R4 and R5 are the same or different and are a hydrogen atom, a C1-4 alkyl group or a C1-4 fluorenyl group. R6 is a C1-4 alkyl group or a C1-4 fluorenyl group. R1 and R3 may also be bonded to each other to form a ring together with adjacent oxygen atoms and carbon atoms. n is 1 or 2, and m is an integer of 0-2. □ |
