    • 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 A 1 to A 8 and E 1 to E 4 are independently selected from the group consisting of hydrogen atoms, halogen atoms, C 1 to C 20 alkyl groups, and the like, and Y represents sulfur or selenium).
    • 本发明提供了一种有机半导体溶液,其可以产生具有可接受的半导体性质的有机半导体膜,同时由于大量的聚合物含量而具有改进的成膜性质。 该有机半导体溶液含有有机溶剂以及溶解在有机溶剂中的聚合物和有机半导体前体。 聚合物相对于聚合物和有机半导体前体的总量的比例等于或大于3质量%。 有机半导体前体具有其中亲双烯体型烯烃通过其双键可除去地键合到由式I)表示的有机半导体化合物的苯环的结构(其中A1至A8和E1至E4独立地选自 由氢原子,卤原子,C1〜C20烷基等组成的基团,Y表示硫或硒)。
