Abstract
  • The design, synthesis and properties of liquid-crystalline semiconducting oligothiophenes containing dithienothiophene (DTT), benzothiadiazole (BTZ)and carbazole (CBZ) rigid cores are described. The effect of molecular structure (shape, size and substitution)on their thermal behaviour and electrical properties has been investigated. Polarised optical microscopy (POM)and differential scanning calorimetry (DSC)analy ses have revealed highly ordered smectic mesophases for most of the newly synthesised compounds. X-ray diffraction (XRD)studies performed at various temperatures have shown that the smectic order is retained in the crystalline state upon cooling across the transition temperature, affording cast films with a more favourable morphology for FET applications.
