Abstract:
1. An organic semiconductor material having a structural formula of the following chemical formula 1: wherein A is a mesogen exhibiting liquid crystallinity, and has a skeletal structure comprising a π-electron ring selected from a group consisting of L-unit of 6 π-electron system ring, M-unit of 8 π-electron system ring, N-unit of 10 π-electron system ring, O-unit of 12 π-electron system ring, P-unit of 14 π-electron system ring, Q-unit of 16 π-electron system ring, R-unit of 18 π-electron system ring, S-unit of 20 π-electron system ring, T-unit of 22 π-electron system ring, U-unit of 24 π-electron system ring and V-unit of 26 π-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, and further wherein the organic semiconductor material has at least one kind of lyotropic liquid crystal phase.
