AbstractNew chiral Schiff bases with a 1,3,4-thiadiazole unit in the rigid core were synthesized (SB1-SB4). These compounds contain a chiral chain derived from (S)-isoleucine and (R)-2-octanol. Their liquid crystalline properties were studied by polarizing optical microscopy, differential scanning calorimetry and X-ray diffraction. Thereby it was found that most of the new compounds exhibit a chiral Smectic C phase. A study of the ferroelectric properties is described.
