Specifications | MSDS | Literature and Reviews
D18-2Br (CAS number 2433725-51-8) has a rigid electron accepting dithienobezothiadiazole (DTBT) core with two electron-donating 5-bromo-4-butyloctylthiophene units. The large side alkyl chains are there to promote solubility for solution processing of the end products that acquire D18-2Br as building block.
D18-2Br has been used for the synthesis of polymer D18 which gave a PCE of 18.22% while Y6 was used as the non-fullerene acceptor.
