Classification: Dithieno[3',2':3,4;2'',3'':5,6]benzo[1,2-c][1,2,5]thiadiazole (DTBT) derivatives, Organic semiconducting materials, Semiconductor Synthesis, Low band gap polymers, OFETs, OLED, Organic Photovoltaics, NFA-OSCs.

Storage Condition: Store in a cool, dry place. Keep the container closed when not in use.

D18-2Br 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.
