4,7-Dibromo-2,1,3-benzothiadiazole is the building block or monomer for organic semiconductors synthesis in the application of light-emitting diodes and photovoltaic devices. Intermediate for the synthesis of i.e. PCDTBT and PCPDTBT.
4,7-Dibromo-2,1,3-benzothiadiazole can be synthesised by using 2,1,3-benzothiadiazole as starting materials to react with bromine in hydrobromic acid. Further bromination of 4,7-Dibromo-2,1,3-benzothiadiazole affords 4,7-bis(5-bromothiophen-2-yl)benzo[c][1,2,5]thiadiazole, a red monomer leading to our pilot polymer PCDTBT which can be used for OPV devices. 4,7-Dibromo-2,1,3-benzothiadiazole is also used for the synthesis of PCPDTBT, a good candidate for the polymer solar cell devices.
