Thiadiazoles

Heterocycles containing nitrogen, oxygen and sulfur have been under investigation for a long time because of their important medicinal properties. The literature survey has described that thiadiazole moieties serve as analgesic, anti-inflammatory, anti-microbial activities, antihypertensive,anticancer, antituberculosis and vasodilator and this ...

Liquid crystalline thiadiazole derivatives: new ferroelectric thiadiazole derivatives

Liquid Crystals, 2002
A 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, 2009
Enlarged 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.
