4,7-Dibromo-5-fluoro-2,1,3-benzothiadiazole
Catalog Number
ACM1347736746-3
CAS
1347736-74-6
IUPAC Name
4,7-dibromo-5-fluoro-2,1,3-benzothiadiazole
Synonyms
Dibromo-FBT
Application
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%
