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 .pi. electron rings, M 8 .pi.
electron rings, N 10 .pi. electron rings, O 12 .pi. electron rings, P 14
.pi. electron rings, Q 16 .pi. electron rings, R 18 .pi. electron rings,
S 20 .pi. electron rings, T 22 .pi. electron rings, U 24 .pi. electron
rings, and V 26 .pi. 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.
