2,1,3-Benzothiadiazole-4,7-bis(boronic acid pinacol ester)
High-purity monomer for the synthesis of small molecules, oligomers and polymers
Available online for fast, secure dispatch
2,1,3-Benzothiadiazole-4,7-bis(boronic acid pinacol ester) is an intermediate for the synthesis of small molecules, oligomers and polymers via Suzuki Coupling reactions. Those small molecules, oligomers and polymers can be printed, spray-coated or spin-coated onto devices for Organic Light-Emitting Diodes (OLED/PLED), Organic Field-Effect Transistors and Organic Photovoltaic devices.
2,1,3-Benzothiadiazole unit is electron deficient so it is employed for the low-band gap semiconducting materials used for OLED and OPV devices, i.e. F8BT and PCPDTBT.
