Description 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.
Uses Fluorinated benzothiadiazole-based conjugated polymers for high open-circuit voltage in organic photovoltaics.
