4,7-dibroMo-5-fluorobenzo[c][1,2,5]thiadiazole Structural

What is 4,7-dibroMo-5-fluorobenzo[c][1,2,5]thiadiazole?

The Uses of 4,7-dibroMo-5-fluorobenzo[c][1,2,5]thiadiazole

Monomer for synthesis of polymers for high power conversion efficiency (PCE) organic solar cells and high mobility OFETs.
Fluorination lowers the polymer HOMO level; resulting in high open-circuit voltages well exceeding 0.7 V.
High-Efficiency Polymer F-PCPDTBT:PC70BM Bulk Heterojuction Organic Solar Cells (OPVs):

JSC = 14.1 mA/cm²
VOC = 0.74 V
FF = 0.58
PCE = 6.2%
