One-Pot Synthesis of 4,8-Dibromobenzo[1,2-d;4,5-d′]bistriazole and Synthesis of its Derivatives as New Units for Conjugated Materials

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
