Title: MICROCRYSTALLINE ORGANIC SEMICONDUCTOR FILM, ORGANIC SEMICONDUCTOR TRANSISTOR, AND METHOD FOR PRODUCING ORGANIC SEMICONDUCTOR TRANSISTOR
Abstract:
[Problem] To provide: an organic semiconductor film which is capable of effectively inhibiting the formation and expansion of cracks, even if patterned or exposed to high heat; an organic semiconductor transistor in which the organic semiconductor film is used; and a method for producing the organic semiconductor transistor. [Solution] Provided are: a microcrystalline organic semiconductor film including a compound which has a molecular weight of 3000 or lower, and which is represented by general formula (1), the size of crystal domains in said microcrystalline organic semiconductor film being at least 1 nm, but not more than 100 nm; an organic semiconductor transistor in which the organic semiconductor film is used; and a method for producing the organic semiconductor transistor. X, Y, and Z represent specific ring-forming atoms. R1 and R2 each represent hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heteroaryl group. R3 and R4 each represent a halogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heteroaryl group. m and n are integers in the range of 0-2.
