摘要：

Tetrathiafulvalene (TTF)-based new organic semiconductors with a long alkyl chain and electron withdrawing substituents are prepared. Among them, cyano-substituted TTF (CnEDT-DC) shows a liquid crystalline phase (Smectic A) at 110-120 degrees C. This compound forms a good thin film on a SiO2 substrate on account of the good affinity of the polar cyano groups to the inorganic substrate, and the field-effect transistor fabricated on SiO2 shows mobility up to 0.02 cm(2) V-1 s(-1).
