4,7-Dibromo-5,6-difluoro-2,1,3-benzothiadiazole CAS NO.1295502-53-2

5,6-Difluoro-4,7-dibromobenzo[c][1,2,5]thiadiazole is the building block/monomer for organic semiconductor synthesis in the application of light-emitting diodes and photovoltaic devices. Extra fluorine atoms on the benzothiadiazole ring makes the compounds more electron-withdrawing when the unit is embedded into low-band gap polymer semiconductors, to introduce better electron affinity and further lower the band gap of the semiconducting materials.
 

We have sublimation apparatus

It is the intermediate for the synthesis of i.e. 4-7-bis(5-bromo-4-2-octyldodecylthiophen-2-yl)-5,6-difluorobenzo[c][1,2,5]-thiadiazole which is the monomer for polymer semiconductor PffBT4T-2OD (PCE11) with high device performance efficiency.
