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.
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.
