Bromothiophene Benzothiadiazole, high purity red monomer
Used for the synthesis of semiconducting polymers
4,7-bis(5-bromothiophen-2-yl)benzo[c][1,2,5]thiadiazole (CAS number 288071-87-4) is a red monomer used for the synthesis of polymer semiconductors i.e. PCDTBT in the application of photovoltaic solar cell devices.
4,7-bis(5-bromothiophen-2-yl)benzo[c][1,2,5]thiadiazole can be targeted by reacting 4,7-Dibromo-2,1,3-benzothiadiazole with N-Bromosuccinimide (NBS) in dichlorobenzene. Further reaction of the red monomer with 9-(heptadecan-9-yl)-2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9Hcarbazole to afford PCDTBT.
Note: This product has been used in our lab for the synthesis of PCDTBT with device performance of 6.7% PCE.
