| Hazard Information | Back Directory | [Description]
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. | [Chemical Properties]
White solid | [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). | [References]
