Abstract
The present invention, the present invention relates to an organic semiconductor material having a benzothienobenzothiophene skeleton, an organic semiconductor ink containing the organic semiconductor material, and an organic transistor using the organic semiconductor material. An object of the present invention is to provide an organic semiconductor material that easily provides a film having a high carrier mobility without the need for a complicated process. It was found that a BTBT derivative having a particular arylene acetylene structure is crystallized by way of a high-order liquid crystal phase having a highly ordered molecular arrangement, and thus the BTBT derivative easily forms a film having a high mobility without requiring complicated heat treatment even when the film is formed by printing. This finding led to the achievement of the object.
