Patent ID: 7259390

Claim:
An organic semiconductor device having an organic semiconductor cell structure form which is prepared by holding an organic semiconductor material having rodlike low-molecular weight liquid crystallinity between opposed electrodes, said organic semiconductor material comprising: a core structure comprising L 6 π electronic rings, M 8 π electronic rings, N 10 π electronic rings, O 12 π electronic rings, P 14 π electronic rings, Q 16 π electronic rings, R 18 π electronic rings, S 20 π electronic rings, T 22 π electronic rings, U 24 π electronic rings, and V 26 π electronic 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 said core structure, said terminal structure being capable of developing liquid crystallinity, said organic semiconductor material having an electron lifetime of at least 4×10 −5 sec and/or a hole lifetime of at least 1×10 −5 sec, and said organic semiconductor cell having a thickness in the range of from 5 μm to 700 μm.
