Patent ID: 7638795

Claim:
A process for producing the organic semiconductor structure comprising the steps of: allowing a liquid crystalline organic semiconductor material to experience or be held at the liquid crystal development temperature of the liquid crystalline organic semiconductor material to once convert the liquid crystalline organic semiconductor material to a liquid crystal state; and cooling the liquid crystalline organic semiconductor material in a liquid crystal state to align and crystallize the liquid crystalline organic semiconductor material; wherein said liquid crystalline organic semiconductor material comprises an organic compound having a core comprising L 6π electron rings, M 8π electron rings, N 10π electron rings, O 12π electron rings, P 14π electron rings, Q 16π electron rings, R 18π electron rings, S 20π electron rings, T 22π electron rings, U 24π electron rings, and V 26π 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, said liquid crystalline organic semiconductor material exhibiting at least one liquid crystal state at a temperature below the heat decomposition temperature thereof.
