Abstract

The one-pot synthesis of 4,8-dibromobenzo[1,2-d;4,5-d']bistriazole, followed by alkylation and Stille coupling to yield three different isomeric derivatives with markedly different optoelectronic properties, is reported. These derivatives show potential as new units in organic oligomers and polymers for electronics applications.
