Abstract
The present invention provides an organic semiconductor solution that can produce an organic semiconductor film having acceptable semiconductor properties while endowed with improved film-forming properties due to substantial polymer content. This organic semiconductor solution contains an organic solvent as well as a polymer and an organic semiconductor precursor dissolved in the organic solvent. The proportion of the polymer in relation to the total of the polymer and the organic semiconductor precursor is equal to or greater than 3 mass %. The organic semiconductor precursor has a structure in which a dienophile-type alkene is eliminably bonded through a double bond thereof to the benzene ring of an organic semiconductor compound represented by formula I) (where A1 to A8 and E1 to E4 are independently selected from the group consisting of hydrogen atoms, halogen atoms, C1 to C20 alkyl groups, and the like, and Y represents sulfur or selenium).
