Abstract
The main object of the invention is to provide an organic semiconductor material whose material designing is easy, and is capable to secure satisfying purity, so that it can be easily used industrially. And further, also to provide an organic semiconductor structure and an organic semiconductor device using the organic semiconductor material. To achieve the object, the present invention provides an organic semiconductor material having a structural formula of the following chemical formula 1:-((A)-(B))-  1 wherein A is a mesogen exhibiting liquid crystallinity; has a skeletal structure comprising a π-electron ring selected from a group consisting of L-unit of 6π-electron system ring, M-unit of 8π-electron system ring, N-unit of 10π-electron system ring, O-unit of 12π-electron system ring, P-unit of 14π-electron system ring, Q-unit of 16π-electron system ring, R-unit of 18π-electron system ring, S-unit of 20 π-electron system ring, T-unit of 22π-electron system ring, U-unit of 24π-electron system ring and V-unit of 26π-electron system ring (whereupon L, M, N, O, P, Q, R, S, T, U and V each represent an integer of 0 to 12, and L+M+N+O+P+Q+R+S+T+U+V is 1 to 12); B has a chain structure with high flexibility; and n is about 3 to about 3000.
