Liquid crystalline thiadiazole derivatives: new ferroelectric thiadiazole derivatives
Liquid Crystals, 2002A series of optically active thiadiazole Schiff's bases were prepared and their liquid crystalline properties were studied. Chirality was achieved by introducing an asymmetric carbon atom into the alkoxy group. Thus, 2-(p -active-alkoxyphenyl-imine)-5-(p-n-alkoxy)phenyl-1,3,4-thiadiazoles were synthesized.

Alkynylated Aceno[2,1,3]thiadiazoles
Organic Letters, 2009Enlarged acenothiadiazoles, which are easily prepared, display attractive optical and electrochemical properties. The annulation of thiadiazole to anthracene gives a stable material with optical properties similar to those of substituted pentacenes.
