Organic semiconductor material and organic semiconductor element

Abstract

Disclosed are an organic semiconductor material having high charge mobility characteristics and an organic semiconductor element. The organic semiconductor material has rodlike low-molecular liquid crystallinity, comprising: a skeleton structure comprising L 6 π electron aromatic rings, M 10 π electron aromatic rings, and N 14 π electron aromatic rings, wherein L, M, and N are each an integer of 0 (zero) to 4 and L+M+N=1 to 4; and a terminal structure attached to both ends of the skeleton structure. The terminal structure can develop liquid crystallinity. The phase angle θ of impedance of the organic semiconductor material is −80°≦θ≦−90° as determined in the measurement of impedance in a frequency f range of 100 Hz≦f≦1 MHz in such a state that the organic semiconductor material in an isotropic phase state is held between a pair of opposed substrates with an interelectrode spacing of 9 μm.
