ABSTRACT:
According to the present invention, a liquid crystal semiconductor capable of exhibiting a highly ordered smectic phase at approximately room temperature, being used for formation of a smectic liquid crystal thin film that is stable at room temperature by a solution process, and showing excellent ambipolar charge-transporting properties, a thin film transistor comprising the same, and the like are provided.Also, the following are provided: a smectic liquid crystal compound represented by the following general formula (1)wherein R1represents a straight-chain alkyl group having 1 to 8 carbon atoms, R2represents an alkyl or alkoxy group having 1 to 8 carbon atoms, and “n” is an integer of 0 to 3; an ambipolar charge-transporting material comprising the smectic liquid crystal compound; an organic semiconductor thin film having a thin film layer comprising the smectic liquid crystal compound; and a thin film transistor comprising the organic semiconductor thin film.
