4,7-DIBROMO-2,1,3-BENZOTHIADIAZOLE

Description

4,7-Dibromo-2,1,3-benzothiadiazole is a white to Light yellow to Light orange crystalline powder and needs to be stored in an inert gas. As an organic intermediate, it is widely used in organic synthesis and pharmaceutical production

Chemical Properties

White solid

Uses

This monomer is used in the synthesis of photoactive acceptor part in low band gap conjugated polymers and oligomers for high performance OPV devices

Uses

4,7-Dibromo-2,1,3-benzothiadiazole is the building block or monomer for the synthesis of light-emitting diodes and conducting polymers for organic electronics. It is used as an intermediate for the synthesis of poly[N-9'-heptadecanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (PCDTBT) and poly[2,1,3-benzothiadiazole-4,7-diyl[4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene-2,6-diyl]] (PCPDTBT).
