摘要：
The synthesis and characterization of a series of tetrathiafulvalenes (1-3) bearing a different number of 4'-cyanobiphenyl-4-yloxy side groups is reported. Compound 3 exhibits a nematic and a smectic A mesophase. In the smectic A phase a peculiar local biaxial order due to the unconventional molecular structure is proposed. A charge-transfer salt derived from 3, namely 3-I-5, also shows mesogenic behaviour.
