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.

The present invention provides a urethane-forming reaction catalyst which is useful for catalyzing a reaction between an isocyanate compound, in particular, an aliphatic isocyanate and a hydroxyl group-containing compound to form a urethane material, which does not affect the performance of the urethane material, and which can be easily removed from the resulting urethane material, and a method for producing a metal compound-free urethane material using the urethane-forming reaction catalyst. The catalyst of the present invention is a urethane-forming reaction catalyst for producing a urethane material by allowing a hydroxyl group-containing compound to react with an isocyanate compound, the catalyst being at least one solid acid catalyst selected from the group consisting of a (A) composite metal oxide in which a metal oxide (A-2) or a non-metal compound (A-3) is carried on a surface of a metal oxide carrier (A-1), (B) zeolite, and a (C) heteropoly acid.
