ABSTRACT:
There is provided a liquid crystalline material, suitable for use as an organic semiconductor material, in which, even when the charge transport distance is long, the charge transport capability is satisfactory, the charge mobility is high, and the dependence of the charge transport properties upon field strength is small. The organic semiconductor material having rodlike low-molecular weight liquid crystallinity comprises: a core structure comprising L 6 π electron rings, M 8 π electron rings, N 10 π electron rings, O 12 π electron rings, P 14 π electron rings, Q 16 π electron rings, R 18 π electron rings, S 20 π electron rings, T 22 π electron rings, U 24 π electron rings, and V 26 π electron rings, wherein L, M, N, O, P, Q, R, S, T, U, and V are each an integer of 0 (zero) to 6 and L+M+N+O+P+Q+R+S+T+U+V=1 to 6; and a terminal structure attached to at least one end of the core structure, the terminal structure being capable of developing liquid crystallinity.
